Frequently Asked Questions

How much does product development cost?+

Depends on complexity. A simple accessory (e.g. phone case) can start from $2,000 (tooling + samples). Complex electronics (e.g. TWS earbuds) typically start from $20,000+.

How long does it take?+

Simple products: 2-3 months. Complex electronics: 6-12 months including certification.

Do I own the mold?+

Yes. The mold is 100% owned by you. We can transfer it to your nominated factory at any time.

Can you help with patent and IP?+

Yes. We can sign an NNN agreement (China-specific NDA), and we can help you file design patents in China.
