Frequently Asked Questions
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 helps prevent slipping during repeated use and is popular with brands whose customers stamp at high volume. The standard production MOQ is 100 pieces per design for both textured and 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?
A 3×4-inch clear stamp block in 12mm PMMA with a printed alignment grid is $4.00 each at 100 pieces, $3.20 at 250, and $2.70 at 500 FOB Shenzhen. Thickness, block size, shape complexity, grip treatment, branding, packing, and quantity move the final price. Send the block dimensions, thickness, shape, quantity, and packing request for an itemized quote.
Do I need an acrylic block to use clear stamps?
Yes — clear photopolymer and cling stamps have no handle of their own, so they need a rigid clear block to mount on before you can ink and press them. The stamp clings to the block by static or slight surface tack; the block gives you something firm to grip and, because it's transparent, lets you see exactly where the design lands. Rubber stamps mounted on cling foam need a block for the same reason. Without a block you can't apply even pressure or place the image accurately.
What size acrylic stamp block do I need?
Choose a block that matches or slightly exceeds your stamp die's footprint — a 3–5mm overhang on each side is a common, comfortable margin. A block smaller than the stamp leaves the edges unsupported and prints unevenly; one much larger is harder to control. For brands producing sets, offering 2–4 block sizes covers most stamp dimensions. See the size and thickness guide above for exact block-to-die pairings.
How do I clean and store acrylic stamp blocks?
Wash the block with mild soap and warm water to remove ink and adhesive residue, then dry it fully before the next use — clean surfaces keep clear and cling stamps sticking properly. Avoid alcohol, acetone, and harsh solvents, which can fog or craze acrylic over time. Store blocks flat or upright away from direct heat and sunlight. Keep clear stamps on their storage sheet, not left on the block, so the cling surface stays tacky.
Are you a factory or a trading company?
We're the factory. Wetop Acrylic has run its own acrylic plant in Shenzhen since 2008, ISO 9001 certified, with cutting, CNC, polishing, laser engraving, and printing in-house — there is no subcontracted middle layer between your spec and the machine. That's why we can hold the same thickness and edge finish across reorders, respond to a quote request within 24 hours, and put every stamp block through 100% inspection against your approved sample before packing.
We're a stamp maker ordering blocks in bulk — how do you handle repeat production runs?
Bulk programs run best as a fixed spec plus scheduled reorders. We keep your approved sample, cutting file, thickness, and edge finish on record, so a repeat run skips re-setup and re-sampling and goes straight to production — 15–20 days for most quantities. The MOQ of 100 pieces applies per size or shape, so you can carry several block formats in one program without over-committing on any single SKU. Send us your size list and expected annual volume and we quote the whole line on one sheet.
