Designer Mahjong OEM for a Two-Collection Production Plan
This manufacturing case shows how a two-collection designer brief can become a production-controlled mahjong program. It is a planning model, not a delivered buyer project. Wetop releases production only after the tile manifest, artwork revision, physical color reference, golden tile, accessories and packing are approved.

Current Mahjong Ordering Reference
MOQ scope: fully custom mahjong tiles start at 50 sets with standard packaging and stock accessories. Accessory customization starts at 250 sets; custom packaging starts at 1,000 sets. We do not paint-fill, sell single sets, make blank-tile prototypes or sell stock sets.
Paid sample tiers: one engraved tile at $40–80 in 5–7 days; a 12-tile color check at $180–320 in 7 days; or a full-set sample at $300–500 in 7–10 days including air freight. Every tier is paid separately and never credited to production.
Standard-spec engraved set, FOB Shenzhen: $58 at 50 sets, $56 at 100, $50 at 200, $49 at 250 and $47 at 500. Construction, artwork, colorway, accessories and packing determine the final quote. Sheet colors are matched from the in-stock range to the buyer's Pantone target and approved on the physical sample — no per-color fees, no casting lead time.
Key Takeaways
- This is a manufacturing planning model, not a delivered-project record; quantities, artwork, color criteria and packaging remain buyer inputs until approved in writing.
- Fully custom mahjong tiles start at 50 sets with standard packaging and stock accessories; accessory customization starts at 250 sets and custom packaging at 1,000 sets.
- A physical tile or color check is the production gate because screen color is not a material approval standard.
- Tile dimensions, face manifest, engraving, color process, accessories and packing must share one revision-controlled bill of materials.
- Standard production is 15–20 days after sample approval, while material, colorway matching and freight timing are confirmed in the quote.
The Challenge
A designer brief may contain two coordinated collections, separate palettes and one retail deadline, but those inputs are not yet a production specification. The factory still needs a playable face manifest, finished tile dimensions, approved artwork revisions, accessory scope, packaging level, quantity and delivery destination.
A Pantone reference in a vector file is also not a physical material approval. Pigmented acrylic and surface print respond differently to light, thickness and finish. The buyer should approve a physical reference under named viewing conditions before production, then keep that reference with the signed artwork and bill of materials.
The two collections can share geometry and inspection logic while keeping separate artwork and color references. A fixed launch date should be planned backward through freight, 15–20 day production, sample review and file corrections; colorways come from the in-stock sheet range, so no casting lead time applies. Wetop confirms those dates in writing after reviewing the final brief.
Our Approach
The plan has three decisions: approve color physically before production, assign each visible feature to a named process, and treat tile geometry, accessories and packaging as one controlled system.
Physical color-swatch matching before production
Licensed artwork is handled under Wetop's standing artwork practice — used only for the owning brand's production, never published, never reused; Wetop does not sign NDAs on mahjong projects, and licensors rely on their trademark and design registrations for enforceable protection. Wetop logs the vector revision and color references, then proposes the appropriate physical sample tier. A buyer may start with one engraved tile, use a 12-tile check for multiple colors or approve a full set when playability, accessories and packing all need review.
Artwork intake: log the face manifest, vector revision and color references. Physical reference: produce the selected tile or color-check tier. Golden tile: approve finished dimensions, artwork position, engraving, color and edge feel. Production release: sign the bill of materials, packing plan and inspection criteria.
A numerical color tolerance is optional, not automatic. If the buyer requires one, the approval must name the formula, instrument, illuminant, physical master and sampling frequency. Otherwise the signed physical tile is the governing color reference.

Cast-in pigment bodies vs UV-printed faces
Body color and face artwork can require different processes. The quote should name the selected construction, print or engraving method and the approval check for each surface.
| Method | Durability | Color fidelity | Cost | Best for |
|---|---|---|---|---|
| Pigmented construction | Buyer approves the physical tile | Solid body or layer color | Sheet-lot and colorway dependent | Tile bodies and backs |
| UV print | Sample validates adhesion and handling | Detailed artwork and gradients | Print area and pass count dependent | Face artwork and licensed graphics |
| Engraving + UV color | Sample validates depth and color placement | Solid characters and indices | Engraving time and color count dependent | Suit characters and markings |
Wetop does not paint-fill mahjong tiles. Engraving and UV color, surface printing, or a layered color construction must be selected from the artwork and confirmed on the sample. The mahjong tile size guide explains how face dimensions constrain artwork, while the custom mahjong tile sets page compares construction options.
Tile geometry and packaging as one system
Shared tile geometry can reduce revision risk across two collections, but Wetop confirms the exact construction, tooling and setup on the quote. The sample should prove tile dimensions, edge feel, rack compatibility and the complete face manifest before either collection enters production.
Packaging is a separate commercial threshold. Standard packaging and stock accessories are available with fully custom tiles from 50 sets; accessory customization starts at 250 sets and custom packaging at 1,000 sets. The packing plan should immobilize the tiles and list every accessory, insert and carton mark before production release.
The quote should keep each commercial layer visible. Tile price, Pantone work, stock or custom accessories, custom packaging, sample fees and freight are separate scope decisions. The five-point FOB ladder applies only to a standard-spec engraved set, so a buyer should not multiply it by a quantity until the construction and included components match that reference.
Approval ownership matters as much as the file list. The buyer names who approves artwork, color, the golden tile and packing; Wetop records the approved revision on the production document. A later artwork, color, count or packaging change triggers a written review of price and timing before production release.
The Results
This planning model is ready for costing only after the buyer supplies the set format, tile dimensions, two artwork packages, color references, accessory scope, packaging level, quantity and destination.
The signed golden tile governs dimensions, edge feel, color and artwork placement. The approved face manifest and packing bill govern count and contents. Wetop confirms the inspection frequency and any numerical acceptance criteria on the production document.
The standard production window is 15–20 days after sample approval. It does not include buyer review time or freight; colorways from the in-stock sheet range add no casting lead time. A quote response is available within 24 hours after the brief is complete.
Buyer decision point: A color that looks right on screen can shift in acrylic; physical swatches and a golden tile are the approval gates that protect the collection.
What This Means for Your Project
Start with the complete set manifest, not only the artwork. Name the tile count, jokers, blanks, dimensions, racks, pushers, dice, mat, bag, packaging and carton marks. That list becomes the basis for sampling and inspection.
Choose the sample tier by decision risk. A single engraved tile checks the core method, a 12-tile check is suited to a multi-color program, and a full set checks playability, count, accessories and packing. Each tier is paid separately and never credited to production.
Treat the $58 / $56 / $50 / $49 / $47 FOB ladder as a standard-spec engraved-set reference, not a quote for this two-collection model. Artwork complexity, construction, Pantone work, accessories and custom packaging can change the final number. Send the full brief through the customization process for a written scope and tiered quote.
