Ways to start

Three ways to launch your own building block sets

Pick the depth of customization that fits your budget, quantity, and launch date. We can recommend a path once we see your brief.

Fastest start

Private label

Choose existing JIESTAR models and launch them with your own box design, logo, and instructions branding. No new tooling, lowest MOQ, shortest timeline.

Best for: Retail chains, gift brands, and online sellers testing a branded range.

Balanced

ODM development

Start from a JIESTAR design and adapt colors, details, scale, or packaging to your market. Our designers handle the model, instructions, and artwork.

Best for: Brands that want differentiated products without a full design team.

Full custom

OEM / new development

Bring your own concept, character, or licensed design. We engineer the model, develop parts or tooling where needed, and produce to your specification.

Best for: Brand owners, licensors, museums, and corporate gift programs.

Capabilities

Custom cooperation capabilities

Custom Solutions is for partners who need more than existing product wholesale, including development, brand presentation, and long-term product line cooperation.

OEM / ODM Customization

Bring a defined design for OEM review, or work with JIESTAR on a product direction through ODM development. Confirm the design and production responsibilities for your project.

Product Co-Development

Develop differentiated building block sets around a partner's market, audience, and launch goals.

Packaging & Brand Customization

Support packaging direction, brand logo placement, and retail-ready presentation planning.

Exclusive SKU

Discuss a dedicated version for your channel or market. Agree any exclusivity scope, duration, and commercial terms in writing.

Exclusive Product Line

Plan a focused product series with consistent category logic, visual identity, and launch rhythm.

Sub-Brand Partnership

Support long-term cooperation where JIESTAR helps partners build distinct product brands.

Prepare your project

Build a brief for your custom building block set

Use these four areas to define the work and make an OEM / ODM proposal easier to assess.

Audience and product concept
Describe the buyer, age range, category, display or play features, and target market. Product links or reference sketches help explain the direction.
Customization scope
Separate model development from box artwork, instructions, logo placement, and naming. Identify the designs and brand assets you can authorize for use.
Quantity and commercial goals
Share the estimated quantity per SKU, target price band, sales channels, and launch date. These inputs guide feasibility and quotation review.
Approval and documentation
Identify who approves the model and artwork, which sample checks matter, and which destination-market documents your team needs to review.

FAQ

Custom project questions

Common questions for OEM / ODM, exclusive SKU, and sub-brand cooperation.

Can I start with private label packaging instead of a new model?

Yes. Discuss an existing product with your packaging and brand presentation as one possible scope. JIESTAR will review the selected SKU, artwork requirements, quantity, and permissions before confirming feasibility.

What determines the MOQ and timeline for a custom set?

MOQ depends on customization depth: private label on an existing model starts lowest, while new parts or tooling need higher quantities. Typical timing is about 15 days for development samples and about 45–60 days for mass production after approval.

How fast will I get a reply and a quotation?

We reply within 24 hours. A quotation follows once we understand the concept, customization scope, and estimated quantity.

Which safety certificates can you provide?

Products are supported by EN71 · ASTM F963 / CPC · CE documentation, and the factory holds BSCI · ISO 9001. Additional third-party tests for your market can be arranged on request; the buyer covers the test fee.

Does a custom SKU include exclusive rights?

Exclusivity needs a separate written agreement covering the product, territory or channel, duration, and responsibilities. Clarify these terms during project review.

How is Custom Solutions different from Wholesale?

Wholesale focuses on existing JIESTAR product supply. Custom Solutions is for OEM / ODM, custom product development, exclusive product lines, and sub-brand cooperation.

Can JIESTAR support a long-term sub-brand partnership?

Yes. JIESTAR can discuss long-term cooperation where product planning, product development, packaging, and brand presentation are considered together.

What information helps JIESTAR review a custom project?

A target market, product category, customization need, and estimated quantity are enough for an initial discussion.

Can custom projects include packaging and logo customization?

Yes. Packaging customization and brand logo customization can be discussed as part of the custom project scope.
