Incredible materials. Incredibly precise craftsmanship.

All frames from nine eyewear are made in Japan, emphasizing the craftsmanship of Japanese artisans.

Each frame undergoes about 250 production steps before final approval. A unique set of tools is created for each frame, which they own and do not resell, preventing copies of the collection. Their carefully selected Japanese manufacturers uphold high production standards.

Frames are hand-assembled and examined microscopically; any inaccuracies result in a complete remake. They use unique Japanese materials, including flexible beta titanium, Takiron acetate, and sustainable polyamide from castor beans, all selected and tested for quality.
