ODM Questions Before You Begin
Share your idea, target market and expected quantity. We can review the design scope and next steps with you.
Who owns the design?
Your original design or the design you provide for your project remains your intellectual property. We can also sign an NDA before you share drawings or concepts.
Do I need to pay for custom molds?
A new design needs its own molds. Molds you pay for are kept at our factory and used only for your products.
How long does ODM development take?
It depends on the design complexity and number of design rounds. We confirm a development schedule once the brief is clear, and a production schedule after the off-tool sample is approved.
What is the Minimum Order Quantity for ODM?
It depends on the design, materials and colors. We confirm the quantity after reviewing your brief, so include your target quantity when you contact us.
