These are eyeglasses designed by Chohei Kotake, which are no longer available. I believe I purchased them at Kaneko Optical. I used to take them in for polishing from time to time and took good care of them. They are still usable, but they have some small scratches on the parts that go over the ears and a scratch on the back of the frame under the right lens due to the years of use. Please check the photos and purchase accordingly. Color: Black Model Number: Unknown * The model number is fading and I was unable to identify it. They do not come with a case, so I will ship them in a different case. Also, the lenses have prescription lenses in them, so please replace them. Color... Black Frame Material... Resin/Plastic Stains, tears, odors, etc... Present
