These are MAXIS eyeglasses. They were dead stock from a friend's eyeglasses shop that closed down. They've been stored away for a long time, but I'm selling them because I have no opportunity to use them. Please note that there may be scratches, stains, distortions, and discoloration due to long-term storage and aging. Demo lenses are installed. There is no case. Size: 53⬜︎18-143 Model number: MXU-211 BR The color is difficult to describe, so please check the images. Made in Japan, acetate and titanium are indicated. Very stylish and unique. They are light because they are titanium. Thank you. Please refrain from price negotiations.
