Acrylic Mahjong Display Case: Fit, Closure and Packing

Prices in this guide are indicative reference estimates. The final written quote depends on the complete custom specification and order scope.

Start with the contents, then design the case

A custom acrylic mahjong display case should be sized around the actual tiles and the way the customer will use it. Confirm the complete inventory, tile dimensions, storage orientation, access and closure before choosing an outside size or wall thickness.

For a shelf display, visibility and convenient access may lead the design. For a case that travels to weekly games, retention, loaded weight and protection need separate attention. A clear case does not become a travel case simply because a lid has been added.

Wetop makes custom acrylic mahjong cases from 50 pieces per design, with price and sample scope confirmed for the construction. You can source a case for tiles made elsewhere; you do not have to order new tile sets to ask about a case. The cases and bags page shows how to separate the storage case, rack sleeve and carry bag in a procurement brief.

Wall thickness follows the loaded construction

Do not choose 4, 5 or 6 mm solely by calling the product budget, standard or premium. Wall thickness works together with case span, joints, base support, divider layout and the loaded weight. A number without that context does not establish strength.

Ask the quotation drawing to distinguish internal usable dimensions from outside dimensions. Wall panels, grooves, lining, dividers and closure parts all consume space. If a buyer supplies only the outside size of an existing box, there may be too little information to reproduce its capacity.

Use the sample to check the full loaded case on a flat surface and during the agreed handling motion. Look for lid binding, unexpected movement at joints, uncomfortable edges and interference with the tile layout. Any carrying handle needs evaluation with the actual loaded case; do not assume a decorative handle is load-rated.

A physical reference case can communicate the intended construction, but it is not permission to copy another brand’s protected artwork. Supply your own branding and identify which functional features you need.

Closure: access and retention are separate questions

A sliding lid, removable lid, hinged lid and hardware closure have different requirements. Choose the opening motion first, then specify what keeps the case closed during its intended use.

Construction	Check before approval	Do not assume
Sliding lid	Track alignment, clearance and full opening travel	The lid is secured against sliding during transport
Removable lid	Lift access and seating around the body	Friction alone provides carrying security
Hinged lid	Hinge position, opening clearance and support	The hinge specification is included without a drawing
Magnetic closure	Alignment and retention in the loaded sample	A magnet is a substitute for a confirmed transit restraint
Mechanical hardware	Attachment, access and operation	A generic cycle rating applies to the assembled case

There is no universal dollar upgrade that makes every case freight-safe. Confirm the proposed hardware and assembled sample. Closure retention is not a substitute for external shipping protection, and a display-case lid is not automatically dustproof or watertight.

UV filtering: request a material specification when needed

Clear appearance does not establish a UV-filtering percentage. If the case will hold light-sensitive objects or needs a specific UV performance requirement, identify the intended exposure and ask for a confirmed material grade and relevant supplier data.

Do not confuse a material being resistant to weathering with the material blocking UV light from reaching its contents. Nor does the label “UV-printed tile” establish how that finished tile will age in a particular environment. The acrylic, colorants, printing and exposure all matter.

For an ordinary storage case, begin with fit, handling and the agreed material. Do not add an unverified “museum-grade” or “95% UV block” claim to your retail copy. Any such claim needs the specified grade, thickness, measurement basis and supporting evidence.

Internal layout: measure the real occupied space

The insert should locate and protect the contents while allowing them to be removed comfortably. Felt lining, dividers and shaped inserts are possible approaches to discuss; no one material is automatically included or mandatory for every mahjong case.

Make a contents map before drawing compartments. List the tile count and storage orientation, spare or blank tiles, dice and any accessories that must fit. A rack stored in the same case can dominate the case length. A case intended only for tiles should not be illustrated as if it also holds four full-length racks.

For a simple row calculation, 14 tiles with a 23 mm face width occupy 322 mm before clearance. At 25 mm each, the same row occupies 350 mm. These numbers do not yet include dividers, lining, end clearance or a groove. They demonstrate why the usable space needs its own dimension.

Specify the actual tile orientation. A row stored face-to-face uses tile thickness along the row, whereas a face-out display row uses face width. Confusing those arrangements can produce a convincing drawing that holds the wrong number of tiles.

Test removal as well as fit. Tiles should not require levering against a brittle edge to get the first piece out. Include finger access or a suitable removal method in the approved layout.

MOQ, sample scope and lead time

Custom acrylic mahjong cases start at 50 cases per design. The unit price, sample fee and schedule depend on the approved dimensions, construction, closure, lining and artwork. The tile sample’s USD 500 fee is not a case sample price.

Likewise, the published USD 200 box-or-bag sample fee should not be silently applied to every engineered acrylic case. Confirm the case-specific sample scope on the quote. Paid samples are separate from production and are not credited.

A useful schedule distinguishes drawing review, sample manufacture, sample transit, buyer approval, production and bulk freight. There is no universal five-day sample or five-week door-to-door promise across every case design. A revision to the tile body can require a revised case even when the case artwork stays the same.

Pairing a case with tiles from another supplier

Send the measured tile body, full inventory and photographs showing the intended layout. A physical reference is useful when edge shape or manufacturing variation affects fit. Agree what reference items are needed before shipping them.

Do not convert a supplier’s nominal dimension into an assumed guaranteed tolerance. Record the measurements and acceptance criteria used for your project. If the tile supplier changes the body between sample and production, recheck the case before releasing the run.

The case brief should include:

• Tile dimensions and complete contents, with orientation shown.
• Whether racks, dice, cards or other items belong inside.
• Display, home storage or regular travel use.
• Preferred opening motion and any retention requirement.
• Branding files, quantity, destination and required arrival date.

The tile specification guide explains the tile-side decisions. The rack page explains the difference between overall rack length and usable ledge length.

Shipping protection is a separate layer

A protective insert inside the case and the export packaging outside it have different jobs. Specify how the lid is restrained, how surfaces are protected from rubbing and how the loaded case is supported in the carton.

Carton quantity and dimensions depend on the finished case and packed weight. Do not assume 12–24 cases per carton or a fixed packaging percentage copied from another product. These details also affect the freight estimate.

If a test protocol or laboratory report is required, request it before quoting. The protocol, packed sample configuration, test provider and acceptance criteria must be confirmed. An internal handling check is not automatically an ISTA 3A report, and no such report is included merely because the product ships internationally.

Compare the final packing photos with the agreed specification before shipment. Keep the approved sample and case drawing available for arrival inspection. Transit damage and specification failures are reviewed case by case with photo evidence.

What a useful case quotation should return

The quote should identify the case dimensions, material and thickness, closure, internal layout, lining or insert, artwork, quantity, sample scope and packing. Any unresolved measurement should be marked as a condition rather than filled with a guessed default.

Approve the loaded sample before production. Confirm access, closure, tile retention, appearance and the agreed handling method. Keep one version of the drawing and sample approval tied to the order so a reorder has a clear reference.

For an accessory-only project, request a case quote with the tile information you already have. For a complete new set, the mahjong configurator collects the tile and accessory choices together. Cases are quoted to their specification rather than assigned a made-up automatic unit price.
