Review drawings, provide manufacturing feedback

Our engineers thoroughly review drawings and ideas to optimize manufacturability and costs. We source the best factories in China, provide detailed cost estimates for prototyping, production, packaging and shipping, and advise on materials, craftsmanship and packaging.

03.

Prototype for design verification and finalization

We assist the factory to make a prototype according to your design.

If you’re developing handmade products, like bags and cases, clothing, or wooden toys, you will see samples that are exactly the same as the bulk order.

We first provide a 3D printed prototype for customer approval before investing in production tooling or mass manufacturing. This confirmation step avoids wasting thousands on new molds for unverified designs. Once the prototype is approved, we officially start tooling and full production.

Approve pre-production samples and finalize packaging

We submit pre-production samples with customized colors and personalized packaging to customers for approval. You don’t have to find packaging factories and designers yourself. We cooperate with many best-price packaging factories and our in-house designers can help to design your packaging and revise it until you’re satisfied.

Production Follow Up & Quality Assurance

We will work with the factory to create prototypes that adhere to your design using the materials chosen when calculating costs. During production, we will oversee progress and conduct quality inspections per your QA guidelines or the approved samples to guarantee the final products meet both your specifications and quality expectations.
