Before You Write

Three questions that save everyone time.

Q: Do I need an appointment to visit the factory?

Yes, please contact us in advance so we can arrange staff to walk you through production and QC. We can also set up a live video walkthrough if travel is not practical.

Q: Will you sign an NDA before I share my design?

Yes. We sign a mutual NDA before reviewing any design files, sketches, or specifications, and we do not show client designs to other customers.

Q: Is there a minimum order to get a quote?

No. We are happy to quote at any volume and will tell you honestly if the quantity is below our MOQ and what the alternatives are. Many clients start with a sample before committing to production.
