Wetop Acrylic manufactures custom American Mahjong sets to NMJL standard with MOQ 50 sets and approximately 20 business day production lead time. Sets can be ordered in 152 (tournament-legal), 160 (retail recommended, with spare tiles), or 166 (Amazon retail standard) tile configurations. All tile faces, tile backs, racks, pushers, cases, and packaging can be customized with original artwork or brand designs. Fully custom tiles — your artwork, engraving, and colorways — start at 50 sets with standard packaging and stock accessories; custom packaging and accessory customization start at 250 sets. Standard tile sizes are 30 × 23 × 13 mm, 32 × 23 × 13 mm, and 36 × 25 × 15 mm cast acrylic PMMA, with custom sizes on request.

What we need to quote you — the 9-point checklist
Every custom mahjong quote needs the same nine decisions. Send them in your first email — or just say "standard" for any item and we apply the default — and you get an itemized quote within 24 hours instead of a week of back-and-forth.
Not sure yet? The defaults below are what most first-time brands choose.
What you get back: an itemized quote within 24 hours — most custom sets land $40–60 per set at the 50–250 set tier, racks and pushers itemized separately. Zero tooling fees: tiles are CNC-cut and engraved, not molded. Want to verify quality first? A single engraved sample tile runs $40–80 (5–7 days); a full custom sample set runs $300–500 including air freight (7–10 days). Sample fees aren't credited to production — the one-off labor far exceeds the fee. Payment: 40% deposit, balance before shipment. Working under NDA is standard for us — our one-way template, or send yours.
One rule before we start
American Mahjong (NMJL standard) has a fixed tile composition — the game can't be played without the right tiles. What you customize is the artwork and presentation, not the tile structure.
Fixed: Tile count · tile types · game rules
Yours to design: Tile face artwork · colors · case · racks · packaging
Choose your tile count
American Mahjong requires more tiles than Chinese or Japanese sets. Always confirm your count before ordering — a 144-tile Chinese set cannot be used to play American rules.
Tournament-legal. Clubs and competitive buyers who specify NMJL-exact.
Best for retail gift sets. Spare tiles prevent returns from a single damaged tile — minimal cost difference.
Matches the most common Amazon retail format. Choose this if you want shelf presence matching established brands.
The 152-tile standard — full breakdown
| Tile type | Count | Notes |
|---|---|---|
| Suit tiles Craks 1–9, Dots 1–9, Bams 1–9 | 108 | 4 of each value per suit |
| Wind tiles North, East, South, West | 16 | 4 of each direction |
| Dragon tiles Red, Green, White | 12 | 4 of each color |
| Flower tiles | 8 | Typically all same design |
| Joker tiles | 8 | Unique to American Mahjong — wildcards |
| Total (playable) | 152 | NMJL standard |
What are blank tiles? Blank tiles in 160/166 sets are plain, unprinted spares for replacements only — not wildcards. If a tile is lost or damaged, an end user can write or sticker the correct face on a blank. Jokers are the only wildcards in American Mahjong.
Design your set
Three surfaces to make the set yours — with one configuration rule up front: fully custom tiles — your artwork, engraving, and colorways — start at 50 sets with standard packaging and stock accessories; custom packaging and accessory customization start at 250 sets. Most orders customize all three surfaces; you can start with tiles-only if packaging comes later.
Tile Face Design
The primary customization surface. Redesign every tile face to your artwork, theme, or brand.
Popular themes: Botanical · Ocean · Ranch · Foodie · Minimalist · Seasonal
Tile Back & Case
The case is the first thing a buyer sees. The tile back is a second branding surface across all 152+ tiles.
Racks & Accessories
Standard sets include 4 racks and 4 pushers. All acrylic components can be color-matched or laser-engraved.

How ordering works
Five steps from first email to finished sets at your door. Most orders receive a quote within 24 hours.
Use the form below or email inquiry@wetopacrylic.com with your intended use (retail / gift / club), tile count (152 / 160 / 166), quantity, and design direction.
Share artwork files, inspiration images, a competitor set you like, or your brand style guide. No design team? A photo or mood board is enough — we handle the rest.
We produce a 2D mockup of all tile faces before cutting any acrylic. Nothing enters production without your sign-off.
First-time buyers or new designs: a small sample run lets you verify color accuracy, tile weight, and packaging fit before committing to full quantity.
~20 business days (varies by complexity). Ships FOB Shenzhen — DDP available. You receive tracking and QC photos before the cargo leaves the warehouse.
Nothing cuts without your approval.
Every project starts with a digital proof. You review every tile face and approve before we produce a single piece.
Preparing your artwork
To produce your tiles, we need print-ready files. You don't need to redesign all 152 tiles individually — only the unique faces.
File & color specifications
How many files do you need?
You only design each unique face once — identical tiles share the same file.
| Design area | Unique faces |
|---|---|
Suit tiles Craks 1–9, Dots 1–9, Bams 1–9 | 27 |
Wind tiles N, E, S, W — or 1 unified design | 1 – 4 |
Dragon tiles Red, Green, White — or 1 unified | 1 – 3 |
Flower & Joker tiles 1 design each | 2 |
Tile back Same on all tiles | 1 |
| Typical total | ~35 files |
Lighter option: We apply your color palette or logo across our standard tile templates. Specify "template color variant" — no 35-file package needed.
