With a rigid cardboard box, the recipient lifts it, admires it for a second, sets it aside — and within a week it is flattened for recycling. With an acrylic box, that same lid reveals an object the recipient sets on a shelf and still sees a year later. That single difference is the whole acrylic vs cardboard gift box decision: cardboard wins on price, weight, and recyclability, while acrylic wins on premium feel and the fact that it is kept. Cardboard costs less per piece and ships lighter; acrylic costs more but earns repeat brand exposure a recycled box never delivers. So the sharper way to run this comparison is not "which material is nicer" — a well-made rigid cardboard box is genuinely beautiful, and I say so to buyers who assume acrylic automatically wins. It is *what happens to the box after the gift is opened*, because that answer runs opposite for the two materials: cardboard does its job at the moment of unboxing and is then recycled, while acrylic's job only starts at unboxing and continues every day the recipient keeps it on a shelf. Buyers who reach for acrylic aren't really buying a nicer box — they're buying cost per kept impression, the brand exposure an object earns over the years it stays in view. This guide breaks the choice down the way we walk B2B buyers through it — cost, premium feel, reusability, durability, branding, weight and shipping, sustainability, and moisture — with every material fact cited so a buyer can verify it, plus a clear rule for when each one wins. --- ## Quick-reference comparison table {#comparison-table} Acrylic and cardboard sit at opposite ends of the gift-box tradeoff: cardboard is the low-cost, lightweight, recyclable packaging; acrylic is the premium, reusable keepsake. The table below lines up the two head-to-head across the nine decision axes packaging and gifting buyers actually weigh, with the third-party-sourced numbers that back the material rows. Read it top to bottom, then jump to the section that decides your program. | Decision axis | Acrylic (cast PMMA) | Cardboard (rigid paperboard) | |---|---|---| | **Unit cost** | Higher — cut, polished, printed, assembled | Lower — inexpensive paperboard, high-speed folding | | **Premium feel** | Glass-like clarity, weight, polished edge | Rich when rigid + foil/emboss; still opaque paper | | **Kept vs. disposable** | Designed to be kept, reused, displayed | Usually recycled after one unboxing | | **Weight** | Heavier; density about 1.2 g/cm³[^makeitfrom-pmma] | Much lighter; paperboard roughly 0.6–0.8 g/cm³[^paperboard-density] | | **Durability** | Rigid, moisture-resistant; can crack on hard drop | Dents, crushes, and absorbs moisture over time | | **Custom branding** | Second-surface print + laser etch under a clear wall — never scuffs off | Full-surface offset/digital print, foil, emboss[^offset] | | **Shipping cost** | Higher — heavier, needs more protection | Lower — light and flat-packable before assembly | | **Recyclability** | Thermoplastic, remeltable but rarely curbside | Widely recycled — US paper/paperboard about 68%[^epa-paper] | | **Sustainability angle** | Reuse (kept for years), not recycling | Recycling + renewable fiber | | **Best fit** | Luxury keepsake, corporate gift, retail hero, display | Volume promo, disposable premium unboxing, e-commerce | The pattern is consistent: every row where cardboard wins is about *doing the packaging job cheaply, lightly, and sustainably*, and every row where acrylic wins is about *becoming a premium object the recipient keeps*. Match the winning column to what your box is actually for, not to a generic "more premium" instinct. --- ## What each material actually is {#what-they-are} Acrylic and cardboard are unrelated materials that fail in opposite ways. Acrylic is polymethyl methacrylate (PMMA), a rigid, optically clear thermoplastic that can be cut, polished, and thermoformed into a box that holds its shape and clarity for years. Cardboard gift boxes are made of paperboard — compressed cellulose fiber, conventionally defined in the paper industry as paper with a grammage above 250 g/m² — usually wrapped or printed and assembled into a rigid "set-up" box. One is a durable plastic; the other is a fiber product that is light, renewable, and recyclable but sensitive to moisture and impact. Acrylic (PMMA) is the same polymer sold under the trade names Plexiglas, Perspex, and Lucite.[^pmma-tradenames] It is optically clear, takes a diamond-polished edge, and can be cast in thick gauges — the reason a quality acrylic gift box has that heavy, glass-like presence a recipient notices in the hand. Rigid cardboard, by contrast, gets its premium feel from construction rather than the material itself: a chipboard or greyboard core wrapped in printed paper, often with foil stamping or embossing, folded and glued into a box that looks and feels far more expensive than the fiber it is made from. Neither material is "better" as a substance — they are built for different jobs. When a buyer tells me the box is a promotional insert or an e-commerce mailer meant to be opened once, rigid cardboard is often the honest answer even though we do not make it; when the box is meant to be kept on a shelf and reused, acrylic is the one that earns its cost. --- ## Cost — unit price vs. cost per kept impression {#cost} Per piece, cardboard is cheaper; per kept impression, the comparison flips. Rigid cardboard boxes carry a low unit cost because paperboard is inexpensive and folding, wrapping, and gluing run at high speed and high volume. Custom acrylic boxes cost more per unit — they are cut, edge-polished, printed or etched, and assembled with finished corners. But cardboard is usually recycled after one unboxing, while an acrylic box is kept and reused, so the honest cost comparison is not unit price — it is cost per impression across the life the box actually has. The way to actually decide this is to separate two buying situations. **High-volume, disposable, packaging-first programs** — e-commerce mailers, promotional inserts, seasonal retail packaging opened once — are where cardboard's unit-cost advantage is real and hard to beat; the box does its job at unboxing and recycling it is the intended end. **Low-volume, keepsake, gift-first programs** are where acrylic's math works: a corporate gift, a luxury retail hero box, a limited-edition keepsake, where the box is meant to be kept, displayed, and reused for years. In that second situation, quoting acrylic against cardboard on unit price alone is the wrong comparison — you are pricing a kept object against disposable packaging, and I say so when a buyer asks why our acrylic quote sits above a rigid-box one. Because custom acrylic is always quoted rather than sold at a fixed price, the real number depends on size, wall thickness, decoration, and quantity — the same variables we work through in the [custom acrylic boxes hub](/products/acrylic-boxes/). One cost note we raise on the first quote: we price landed cost including freight, not just FOB, and buyers should ask every supplier for the same basis, because acrylic's weight makes freight a bigger share of the total than it is for lightweight cardboard. The way I coach buyers to sanity-check the premium is to divide the unit cost by the impressions the box actually delivers. A cardboard box priced low but recycled after one open delivers its cost across a single unboxing. An acrylic box priced higher but kept on a shelf for a year or more delivers its cost across hundreds of daily glances by its owner and everyone around them. When you run the two boxes through that lens, the acrylic premium usually looks smaller than the raw unit-price gap suggests — not because acrylic is cheap, but because its impressions are spread over a life the cardboard box never has. This is not a reason to always choose acrylic; a genuinely disposable program should still buy cardboard. It is a reason to stop comparing the two on unit price alone, which is the single most common way I see buyers reach the wrong material. --- ## Premium feel — where each material earns its shelf presence {#premium-feel} Both materials can feel premium; they get there by opposite routes. A rigid cardboard gift box earns its premium feel through construction — a heavy greyboard core, a tight paper wrap, foil stamping, embossing, and a satisfying magnetic-lid close. Done well, it is genuinely luxurious at the moment of unboxing. An acrylic box earns its premium feel through the material itself — optical clarity, a diamond-polished edge, and a cool, glass-like weight that reads as "expensive object" before the recipient even opens it. The difference is *when* the premium feel peaks and *how long it lasts*. This is the axis buyers most often oversimplify, so I slow it down. Cardboard's premium feel is a peak-and-fade curve: it is at its best in the sealed, unopened state and during the first open, then it does its job and the impression ends when the box is recycled. Acrylic's premium feel is a plateau: it is high at unboxing and stays high every day the box sits on a desk or shelf, because the clarity and weight do not wear off. Neither curve is wrong — they suit different goals. If the goal is a spectacular one-time unboxing moment, especially for content or e-commerce where the reveal is the point, high-end cardboard delivers it cheaply and beautifully. If the goal is a lasting brand object the recipient chooses to keep in view, acrylic's plateau is worth the premium. The moment a buyer's brief mentions "something they'll keep," "on their desk," or "reusable," that brief is quietly describing an acrylic box, and the plateau is exactly why.
Perceived brand value over time for an acrylic gift box versus a rigid cardboard gift box. A line chart with time on the horizontal axis from unboxing to years later. The cardboard line starts high at unboxing then drops toward zero after the box is recycled within days. The acrylic line starts high at unboxing and stays near its peak for years because the box is kept and reused. Conclusion: cardboard delivers a peak-then-fade unboxing impression, acrylic delivers a sustained impression as a kept keepsake. Brand value over the box's life Cardboard peaks at unboxing then fades; acrylic holds because it is kept. Unboxing Days Months Years High Low Cardboard recycled after unboxing Acrylic kept and reused for years Cardboard's impression ends when the box is recycled. Acrylic keeps returning brand exposure every day it stays on the recipient's shelf — the reason to pay its premium.
Cardboard delivers a peak-then-fade unboxing impression; acrylic holds its perceived value for years because the box is kept — the core argument for the acrylic premium.
--- ## Reusability and keepsake value — acrylic's decisive advantage {#reusability} For a box meant to be kept, acrylic is built for reuse in a way cardboard is not. A cast acrylic gift box is rigid, moisture-resistant, and holds its clarity, so recipients repurpose it as a display case, a desk organizer, or a storage box — and every time they do, the brand on the box gets seen again. A rigid cardboard box can be reused for casual storage, but paperboard dents on impact, softens with humidity, and shows wear at the corners, so most are recycled after one use rather than kept.[^epa-paper] Reusability is the single axis where acrylic pulls decisively ahead, and it is the whole economic case for the material. This is the failure mode buyers underrate when they compare on unit price alone. A cardboard box is priced as packaging because it behaves as packaging: it protects and presents the gift once, then its useful life ends. An acrylic box behaves as a product, because it survives the transition from "packaging" to "thing on the shelf" — the moment where cardboard almost always drops out. In practice, the buyers who choose acrylic are not really buying a nicer box; they are buying repeat brand impressions from an object the recipient chooses to keep, and they are willing to pay a higher unit cost because that keeping is the point. When a brief describes a keepsake, a collector item, a limited edition, or a gift "they'll actually keep," the reusability requirement has quietly ruled cardboard out, and the honest recommendation is acrylic even before we talk about clarity or branding. There is a second-order effect here worth naming, because it is the part buyers who choose acrylic tend to appreciate only after the fact. A kept box does not just deliver more brand impressions to its owner — it delivers them to everyone who sees it on the owner's shelf, desk, or counter. A cardboard box that is recycled reaches exactly one person once; an acrylic box that lives on a desk in an open office, a retail counter, or a display shelf is seen by every visitor, colleague, or customer who passes it, for as long as it stays there. That ambient, third-party exposure is invisible on a unit-cost spreadsheet and is precisely the value a keepsake box is bought for. We build this end of the field across our [custom acrylic gift boxes](/products/acrylic-boxes/acrylic-gift-boxes/) line, which is designed from the start to be kept rather than discarded. --- ## Durability and moisture — how each material fails {#durability-moisture} Cardboard fails to moisture and impact; acrylic fails to hard drops. Paperboard is a fiber product, so it absorbs humidity, warps in damp storage, softens at the edges, and crushes or dents under impact — which is why a cardboard box that traveled through a humid supply chain can arrive looking tired. Cast acrylic is rigid and moisture-resistant, so it shrugs off humidity and holds its shape, but it is a brittle thermoplastic that can crack or chip on a hard fall. The materials fail in opposite directions, and the right one depends on what your box has to survive. The practical distinction is about *environment and expected life*. For a box that ships flat, gets assembled, holds a gift for one presentation, and is then recycled, cardboard's moisture and impact sensitivity rarely matters — it only has to survive the journey to the unboxing, and good packaging design and a protective outer mailer handle that. For a box that is meant to live on a shelf for years — in a kitchen, a bathroom, a humid climate, or a display case — acrylic's moisture resistance and rigidity are exactly what keep it looking new, where a cardboard box would slowly degrade. The tradeoff is drop risk: an acrylic box that falls off a shelf onto a hard floor can crack, where a cardboard box would dent and survive. In gifting and display use, hard drops are rare and humidity exposure is constant, so acrylic's failure mode is the one buyers can more easily design around. Wall thickness is the main lever on acrylic's drop resistance, and getting it right is a spec decision worth making deliberately — we cover the numbers in the [acrylic box wall thickness guide](/guide/acrylic-box-wall-thickness-guide/). --- ## Custom branding — different strengths, not a clear winner {#custom-branding} Both materials brand well; they win on different terms. Cardboard accepts rich, full-surface decoration cheaply — offset or digital printing across the entire wrap, foil stamping, embossing, and spot varnish[^offset] — so for all-over artwork and tactile print effects at low cost, it is hard to beat. Acrylic brands differently: you print artwork on the second surface (the inside of a wall), viewed *through* the clear acrylic so the material itself protects the print, or laser-etch a logo that reads understated and premium. Cardboard's edge is print richness and cost; acrylic's edge is that the branding never scuffs off because it is sealed under the wall. This is the axis where the honest answer is "it depends on whether the box is kept." When the box is disposable, cardboard's decoration options are genuinely excellent and cheaper — the print only has to look perfect once, at unboxing, and full-surface offset with foil delivers a luxurious result at a fraction of acrylic's cost. But when the box is a kept object, cardboard's branding ages with the box: the printed wrap scuffs at the corners, foil rubs, and edges soften, so the branding degrades exactly as the recipient is meant to keep looking at it. Acrylic's decoration is in a different class for that long-life case: - **Second-surface printing.** Full-color artwork sealed under the clear wall, viewed through the acrylic, giving a glossy depth effect that survives handling and daily display intact — the reason it dominates our keepsake and corporate-gift orders. - **Laser etching.** A frosted logo cut into the surface that reads as understated and premium precisely because it does not shout, and cannot rub off the way foil can. - **Color and finish.** Beyond clear, acrylic runs frosted, tinted, or mirrored to match a brand palette while still carrying a printed or etched mark. - **Interchangeable inserts.** A printed insert that drops behind a clear wall, so seasonal or campaign artwork can change without re-tooling the box. Cardboard's branding, by contrast, is superb at the moment of the reveal and fades with the box. So the branding verdict tracks the same question as everything else: for a disposable premium unboxing, cardboard's print options win on cost and richness; for a kept keepsake, acrylic protects the branding for the life of the object. A boutique gift-box program that needed both premium presentation and repeat-order consistency is walked through in our [acrylic gift box boutique rollout case study](/case-studies/acrylic-gift-box-boutique-rollout/). --- ## Weight and shipping cost — cardboard's quiet advantage {#weight-shipping} Cardboard is far lighter, and that shows up on every freight invoice. Paperboard runs roughly 0.6–0.8 g/cm³ depending on grade,[^paperboard-density] while cast acrylic sits near 1.2 g/cm³,[^makeitfrom-pmma] so a comparable acrylic box weighs more — often substantially more once you account for the thicker walls acrylic needs for rigidity. On top of raw density, cardboard ships flat and is assembled later, while acrylic ships as a finished rigid object that needs more protective packing. For a high-volume gifting program, that weight difference is a real, recurring cost line, not a rounding error. This is the axis where I tell buyers not to romanticize acrylic. If the program is large-volume and cost-sensitive, cardboard's light weight and flat-pack shipping compound into meaningful savings across thousands of units — savings that acrylic simply cannot match, because you are shipping a denser material in a bulkier finished form. The way to keep acrylic's shipping cost sane is to spec it deliberately: wall thickness drives both the premium feel and the shipping weight, so the goal is enough thickness to feel substantial without overbuilding a box that is heavy to ship and heavy in the hand. Thicker is not automatically better. On a kept keepsake at lower volume, the freight premium is easy to justify because it is spread over an object with a long life; on a disposable box at high volume, the same freight premium is exactly the kind of cost that tips the decision back to cardboard. We flag the weight-versus-thickness math before a buyer overbuilds the walls, and it is one of the reasons the [custom acrylic boxes hub](/products/acrylic-boxes/) treats wall gauge as a spec decision rather than a "more is better" default. --- ## Sustainability — an honest tradeoff, not a slogan {#sustainability} On sustainability, cardboard leads on recycling and acrylic leads on reuse — and buyers should not conflate the two. Cardboard's case is strong and verifiable: US paper and paperboard are recycled at about 68%, the highest recycling rate of any packaging material,[^epa-paper] and paperboard is made from a renewable fiber and is widely accepted curbside. Cast acrylic is a thermoplastic that can technically be remelted, but it is rarely collected in curbside recycling programs, so in practice most acrylic is not recycled. If curbside recyclability and renewable material are the buyer's priority, cardboard is the honest answer. We state this plainly because overclaiming acrylic's green credentials would be exactly the kind of unverifiable marketing we keep off this site. Acrylic's genuine sustainability argument is not recycling — it is *reuse and displacement*. A box that is kept and reused for years is a box that displaces the repeat production, shipping, and disposal of the disposable packaging that would otherwise be bought and thrown away over that same period. That is a real environmental benefit, but it is a different claim than "recyclable," and it only holds if the box is actually kept — which loops back to whether the program is keepsake-first or packaging-first. The honest framing I give buyers is this: if your sustainability story is built on curbside recyclability and renewable fiber, cardboard wins outright; if it is built on durability and reuse displacing single-use packaging, acrylic has a legitimate case. Choose the argument that matches your box's real life, and don't stretch either material into a claim it can't support. --- ## The unboxing moment — where cardboard is genuinely strong {#unboxing} For a one-time unboxing built around the reveal, cardboard is often the better tool, and I say so without hedging. A rigid cardboard box with a magnetic lid, a tissue liner, and a foil-stamped inner wrap delivers a theatrical open — the lid lifts, the tissue parts, the product is revealed — that is genuinely hard to beat, and it is cheap enough to run at volume. For e-commerce brands whose unboxing is content, for subscription boxes, and for seasonal retail where the box is opened once and photographed, cardboard's staged reveal is exactly the right instrument, and acrylic's clarity actually works against it because a clear box shows the product before the open. This matters because "premium" and "unboxing experience" are not the same requirement, and buyers sometimes reach for acrylic when they actually want a better reveal. If the goal is the moment of opening — the anticipation, the layered reveal, the shareable first look — cardboard's ability to hide, layer, and stage the contents is a feature acrylic cannot match, since acrylic's whole appeal is that you can see through it. If the goal is a lasting object the recipient keeps, acrylic wins for the reasons covered above. The clean way to decide is to ask whether the box's job ends at the open or continues after it. A box whose job ends at the reveal should almost always be cardboard; a box whose job continues on a shelf should almost always be acrylic. Conflating the two is the most common mistake I see in gift-box briefs, and separating them usually settles the material in a sentence. --- ## Where rigid plastic and wood fit {#other-materials} Acrylic and cardboard are two of several gift-box materials; rigid non-acrylic plastics and wood round out the premium field. Other clear plastics — PETG and polycarbonate — can also make a see-through gift box: PETG is a lower-cost, easier-to-form clear plastic, and polycarbonate is a tougher, more impact-resistant one, but neither matches cast acrylic's optical clarity and polished-edge premium look. Wood reads warm and natural like a high-end keepsake, but is heavier, costlier to finish, and harder to make in complex clear-window forms. Slotting these together makes the acrylic-vs-cardboard choice clearer by showing what each material is really for. **PETG and polycarbonate** are the clear-plastic alternatives when cost or impact resistance outranks premium clarity — a fuller comparison of those against acrylic is in our [acrylic plastic box vs polycarbonate vs PETG guide](/guide/acrylic-plastic-box-vs-polycarbonate-vs-petg/). **Wood** is the artisanal keepsake choice for a rustic or heritage-brand feel, accepting the weight and cost for the natural look. **Cardboard** is the light, recyclable, low-cost packaging for disposable premium unboxing and volume programs. **Acrylic** is the clear, brandable, reusable keepsake for luxury gifts, corporate gifting, and retail hero boxes where the box is meant to be kept. If your shortlist has come down to acrylic vs. cardboard specifically, you have usually already decided the box is either premium-disposable or premium-keepsake — and the earlier sections settle which material serves that intent. --- ## Decision framework — which box for which gift {#decision-framework} Match the material to what happens to the box after the gift is opened. Boxes that are opened once and recycled — e-commerce mailers, promotional inserts, seasonal retail packaging, high-volume programs — point to cardboard's low cost, light weight, and recyclability. Boxes that are meant to be kept, reused, and displayed — luxury keepsakes, corporate gifts, limited editions, retail hero boxes — point to acrylic's premium feel, durability, and reusable brand presence. I run new buyers through the same five questions, and they settle the choice in about a minute: 1. **Is the box meant to be kept, or opened once?** Kept and displayed → acrylic, decisively. Opened once → cardboard is fine. 2. **What is the volume and cost sensitivity?** Very high volume, cost-driven → cardboard's unit cost and shipping weight win. Lower volume, keepsake-driven → acrylic's cost-per-kept-impression wins. 3. **Is curbside recyclability part of the brand promise?** Yes → cardboard leads on recycling and renewable fiber. No / reuse story → acrylic's durability case applies. 4. **Where will the box live?** On a shelf, in humidity, for years → acrylic resists moisture and holds clarity. In a drawer or recycled → cardboard is enough. 5. **Does the branding need to survive the box's life?** Yes → acrylic seals print under a clear wall so it never scuffs. Only until unboxing → cardboard's rich print is cheaper. When most answers point one way, that is the material. When they split — say, a premium program that is guest-facing but also high-volume and cost-sensitive — the tiebreaker is whether the box is genuinely meant to be kept. If it is, acrylic's reusability justifies the premium; if it isn't, you are paying keepsake prices for packaging, and cardboard is the honest call. In my experience, the moment a buyer describes the box as something the recipient will keep and display, the decision has already made itself. Once it has narrowed to acrylic, [send us your gift-box brief](/contact/?source=acrylic-vs-cardboard-gift-box-buyer-guide) to pressure-test the spec — the sample tells a buyer more than any spec sheet. --- ## How to spec a custom acrylic gift box if that is your pick {#spec-acrylic} If the decision lands on acrylic, seven spec lines turn a vague request into an accurate quote. Most box quotes stall on missing basics rather than hard questions, so pinning them down before writing to any factory produces a faster, tighter, comparable quote — and protects a buyer from a supplier quoting a cheaper build than they pictured. The seven lines that matter: 1. **Dimensions, and which kind.** State outside or inside dimensions explicitly — a box that must *hold* a 200 mm item is a different object than one that *measures* 200 mm. 2. **Wall thickness.** This drives both the premium feel and the shipping weight; state the number rather than "thick," and see the [acrylic box wall thickness guide](/guide/acrylic-box-wall-thickness-guide/) for the tradeoffs. 3. **Material grade.** Specify cast acrylic — it polishes to a cleaner edge and comes in the thick gauges a substantial keepsake box needs. 4. **Lid and closure.** Slide-on, hinged, magnetic, or friction-fit — each changes tooling, cost, and the unboxing feel. 5. **Decoration.** Second-surface print, laser etch, insert, or plain clear — with vector artwork if a logo is involved. 6. **Quantity and cadence.** Against our 50-piece MOQ, and whether this is a one-off test or a repeating program. 7. **Destination and terms.** So the quote can include freight from day one, on a landed basis you can compare like-for-like — which matters more on heavy acrylic than on light cardboard. The wholesale path itself is shorter than most first-time buyers expect: a 50-piece MOQ per design, samples in 3–5 days, and production in 15–20 days, with every piece inspected before packing under our ISO 9001 quality system. The sample stage is where these programs are actually decided — it is the one moment a buyer holds the exact corner joint, edge polish, print quality, and clarity the production run will be measured against. For a branded keepsake program especially, I tell buyers to approve nothing from a render; the physical sample is the whole point of the exercise, and we ship it in days. --- ## How we sourced this comparison {#methodology} The material claims in this guide are drawn from third-party standards, regulatory data, and materials references — not from internal Wetop testing. Acrylic's density (about 1.2 g/cm³) comes from published PMMA material data;[^makeitfrom-pmma] paperboard's density range from paper-industry material references;[^paperboard-density] the paper and paperboard recycling rate (about 68%, highest of any packaging material) from US EPA municipal-waste data;[^epa-paper] and cardboard's decoration options (offset and digital printing, foil, emboss) from printing-process references.[^offset] Acrylic's food-adjacent and thermoplastic properties, and its trade-name lineage, come from published PMMA references.[^pmma-tradenames] Where the material behavior is settled — paperboard absorbs moisture and is widely recycled, cast acrylic is rigid and moisture-resistant — we state it directly. Where a number depends on grade or program, we give a range and cite the source so you can verify it against your own conditions. Wetop does not run a materials test lab; we manufacture custom acrylic boxes and inspect every order piece-by-piece before ship, and our contribution to this comparison is the buyer-facing pattern of which material fits which gift, learned across 2,000+ custom projects for buyers in 25+ countries.
