Acrylic Stamp Blocks
For craft supply brands and stamp manufacturers supplying the retail market — not individual crafters. Bulk-manufactured to your spec.
An acrylic stamp block is a clear PMMA platform used to mount rubber or photopolymer stamps, allowing the user to see the stamp pattern through the block for precise alignment on paper, fabric, or card stock before pressing. Wetop Acrylic manufactures custom acrylic stamp blocks — also called plexiglass stamp blocks or clear stamping blocks — in rectangular, round, and custom shapes for craft supply brands, stamp manufacturers, and stationery wholesalers. MOQ 50 pieces.

Acrylic Photo Blocks → ›Stamp Block Size & Thickness Guide
An acrylic block for stamps should match or slightly exceed the stamp die footprint — typically 3–5mm clearance per side. Thickness determines hand feel and structural rigidity: 3mm for lightweight tester blocks, 5–6mm for standard retail, 8–10mm for premium kits.
| Stamp Die Size | Recommended Block Size | Recommended Thickness | Best For |
|---|---|---|---|
| Up to 2×2" (50×50mm) | 2×2" (50×50mm) | 3mm | Tester sets, lightweight sample packs |
| 2×3" (50×76mm) | 2×3" (50×76mm) | 5mm | Standard retail stamp sets |
| 3×4" (76×102mm) | 3×4" (76×102mm) | 5mm | Greeting card, scrapbooking stamps |
| 4×6" (102×152mm) | 4×6" (102×152mm) | 6mm | Large background stamps |
| 6×4" (152×102mm) | 6×4" (152×102mm) | 6–8mm | Wide border and panoramic stamps |
| 6×9" (152×229mm) | 6×9" (152×229mm) | 8–10mm | Full-page background stamps |
| Custom / irregular | Die footprint +3–5mm | 5–8mm | Custom die-cut profiles |
All sizes fully customizable. Clearance (block overhanging the die) is a design preference — some brands prefer flush-edge fit, others 5–10mm overhang for better grip.
How a Stamp Block Assembly Works
The acrylic block is the handle — you hold it on top and look down through the clear material to see the stamp die pattern below. This see-through alignment is the entire reason acrylic replaced wood as the standard stamp block material.
Diamond polishing is standard on every stamp block — producing crystal-clear edges that catch and transmit light on 5mm and thicker blocks. On 3mm blocks, the edge is too thin to appreciate the polish, so we use flame polishing for a smooth, clean finish.
Why Craft Brands Choose Clear Acrylic Stamp Blocks
Clear acrylic stamp blocks let the user see the rubber stamp pattern through the block before pressing — the single most important functional advantage over wood or foam alternatives. That visibility means precise placement, cleaner stamped images, and fewer wasted sheets. For craft supply brands, it translates directly into fewer customer complaints and higher repeat purchase rates.
| Clear Acrylic | Wood | Foam | |
|---|---|---|---|
| See-through alignment | Yes — see die through block before pressing | No | No |
| Custom shapes | Laser-cut or CNC to any profile | Limited | Limited |
| Branding | Laser engrave or print directly on surface | Sticker or paint only | No |
| Durability | High — scratch-resistant, won't warp | Warps with moisture | Low — compresses over time |
| Weight | Lightweight (1.19 g/cm³) | Heavier | Very light but unstable |
| Edge finish | Diamond or flame polished — glass-like clarity | Cut edge only | No edge |
| Cost (bulk, 200+ pcs) | Mid-range | Similar | Lowest |
| Best for | Retail stamp sets, premium kits | Rustic/artisan craft brands | Low-cost tester giveaways |
Stamp blocks sold as "plexiglass stamp block" or "perspex stamp block" in European markets use the same clear PMMA material. Related guide: Clear vs Frosted vs Colored Acrylic

Who Orders Custom Acrylic Stamp Blocks?
Acrylic stamp blocks are ordered by craft supply brands, stationery wholesalers, independent stamp makers, and scrapbooking kit companies — businesses that need consistent quality at volume, not one-off crafters buying single blocks from a craft store.
Craft Supply Brands
Retail-packaged stamp block lines for craft stores and online channels. OEM supply for brands selling under their own label — private labeling, custom retail packaging, and consistent batch quality across reorders.
Stationery Wholesalers
Bulk blank blocks in standard sizes for distribution to retailers, print shops, and craft studios. Typically 200–2,000 units per size per order. Need consistent dimensions and edge quality across every batch.
Indie Stamp Makers
Small-batch custom shapes with brand logo engraving. Hexagonal, arch, and tag-shaped blocks that match their stamp die collections. MOQ 50 pieces makes small runs viable for emerging brands.
Scrapbooking & Craft Kit Brands
Multi-size stamp block sets bundled into retail kits. 2–4 block sizes per set with printed cardboard sleeve packaging. Popular for gift sets and seasonal collections.
What Affects Acrylic Stamp Block Pricing?
Custom acrylic stamp block pricing depends on four factors: acrylic thickness, block size, shape complexity, and order quantity. Diamond polishing is included on every block. We don't publish fixed price lists because every order is custom — but here's what moves the number so you can plan your budget accurately.
Acrylic Thickness
The biggest variable. A 10mm block uses more than 3× the material of a 3mm block. Most retail stamp blocks use 5–6mm — the sweet spot of hand feel and cost.
Block Size
Moving from a 2×3" block to a 4×6" block roughly doubles material per unit. Multi-size sets are priced by total acrylic area across all sizes.
Shape Complexity
Rectangles and circles are most cost-efficient. Custom die-cut shapes require additional CNC/laser setup — a per-project cost that spreads across order quantity.
Order Quantity
The biggest per-unit price drop falls between 50 and 200 pieces. Above 500, cost continues to decrease at a smaller incremental rate.

Do you offer grip texture on acrylic stamp blocks?
Yes. We offer three grip options: smooth polished sides (standard), fine sandblasting on the side faces for a matte non-slip grip, and laser-etched grip strips across the top surface. Grip texture prevents the block from slipping during repeated use and is popular with brands whose customers stamp at high volume. MOQ for grip-texture variants is the same 50 pieces as smooth blocks.
How does cling foam attach to an acrylic stamp block?
Cling foam (repositionable foam mounting sheet) adheres to the flat underside of the acrylic block using the foam's own pressure-sensitive adhesive layer — no additional glue needed. The foam grips the rubber or photopolymer stamp die during use and releases cleanly when swapped. We supply blocks with pre-applied cling foam for brands that want a ready-to-use product, or blank blocks for brands that apply their own foam in-house.
Can you package acrylic stamp blocks for retail resale?
Yes. Three retail packaging options: individual clear bags with header cards (for hanging display), printed cardboard sleeves with product info (most popular for craft store shelves), and branded gift boxes for premium stamp sets. Retail packaging is produced alongside the blocks — same factory, same shipment. MOQ for custom retail packaging is 200 pieces. We coordinate both in a single order.
What affects the price of acrylic stamp blocks?
Four factors: acrylic thickness (3mm vs 10mm is the biggest variable — thicker uses more material), block size (larger footprints use more material and cutting time), shape complexity (rectangles are simplest; custom die-cut shapes need additional CNC or laser setup), and order quantity (biggest price break falls between 50 and 200 pieces). Diamond polishing is included on every block. For an exact quote, send us your block dimensions, thickness, shape, and quantity.
