How to Make Blind Box?

What Is a Custom Blind Box?

A custom blind box is a sealed retail package containing one mystery figure from a pre-defined series. The buyer knows the series, the price and the rough style — but does not know which specific variant they will receive until they open the box. The surprise is the product. The thrill of opening drives repeat purchase, set completion, and a healthy secondary market for sealed collectibles.

Rarity Ratios & How to Design a Blind Box Series

RRarity ratios are the most critical commercial decision for any blind box series. They shape collector behaviour, perceived value of chase and secret figures, repeat purchase rates, and resale market demand. Below is our recommended probability setup for a debut series:

  • 8 base designs: 1 in 8
  • 2 rare colorways: 1 in 24
  • 1 chase figure: 1 in 48
  • 1 secret figure: 1 in 144

How the packing math works

For every batch of 144 sealed boxes, the total 144 figures are allocated following the above odds:

  • 18 units across the 8 base designs
  • 6 rare colorway units
  • 3 chase figures
  • 1 secret figure

Our packing station uses randomised sorting. Variants are shuffled and sealed into inner bags before outer boxes are packed. The full series BOM will be reviewed and confirmed with you before production is finalised.before production locks.

Our 12-Step Custom Blind Box Production Process

Blind box projects take longer than standard toy orders due to multiple character variants, inner sealing, and mixed-SKU random packing. Below is our streamlined workflow.

  1. Project Brief & Design Confirmation Send character art, variant count, target ratio and retail price. We review specs after NDA execution.
  2. 3D Sculpting Our in-house team sculpts all variants in ZBrush. Chase and secret figures share base models with swap parts to cut mold costs.
  3. PU Prototype & Hand Paint Sign-off One polished, primed PU prototype per variant. Hand painted samples for your design approval.
  4. Pantone Color Matching & Master Sample Approval Match colors using your Pantone codes or reference photos. Ship finished master samples for final sign-off.
  5. Mold Design & Fabrication Split approved samples by color layers. Run mold flow simulation on vinyl parts to prevent weld lines on faces. Aluminum rotocast molds for vinyl bodies; steel injection molds for PVC/ABS parts. CNC machined and short-shot tested.
  6. Mass Production & Part Finishing Rotocast vinyl bodies and inject PVC/ABS accessories. Trim sprues and grind parts smooth.
  7. Painting, Pad Printing & QC Check Spray base coats, hand paint fine details, apply pad printing for faces and logos. Each variant inspected at dedicated QC station.
  8. Inner Seal & Outer Box Assembly Place figures into matte silver foil bags or plastic capsules, heat/ultrasonic sealed. All variants look identical externally. Pack sealed units into printed retail boxes, insert variant codes and instruction cards, glue and tamper-seal boxes.
  9. Mixed-SKU Random Packing Pack retail boxes into master cartons following your agreed ratio. Random shuffle for even distribution. Carton labels include ratio manifest for customs.
  10. Final QC & Shipment 10% sampling inspection, master carton drop test and ratio audit. Palletized goods ready for FOB Shenzhen shipment.

FAQ

1. What materials can be used for custom blind‑box figures?

PVC and ABS are the mainstream choices for mass‑produced blind boxes, delivering stable detail reproduction and cost‑effective injection molding. Soft vinyl (sofubi) creates classic hollow soft‑texture collectibles. Resin is mainly used for high‑detail prototype samples. We also support plush‑fabric blind‑box dolls.

2. Can you set custom probability ratios for secret / chase figures?

Yes. We follow your defined probability rules for regular, rare and secret chase figures. Our factory implements strict internal batch‑packing management to meet your published series odds.

3. What deliverables do I need to supply to start a blind‑box project?

You can provide character sketches, reference art, or finished 3D files. Please also share your planned character list and chase‑figure probability requirements. Our design team can complete full‑series 3D sculpting from 2D references.

4. What is the difference between static blind‑box figurines and mini action‑figure blind boxes?

Static blind‑box figures have no movable joints, lower mold‑tooling cost and are the most common retail format. Mini action‑figure blind boxes add articulated joint structures and interchangeable small accessories, which increase mold complexity and overall project cost.

5. What are main factors affecting blind‑box project cost and MOQ?

Mold‑tooling cost rises with the number of unique characters in one series. Material choice, painting complexity and full‑custom packaging also influence pricing. MOQ is negotiable; contact our sales team with your series brief for a formal quotation.
