This is a pair of DOPE sunglasses. They were included as a bonus with a B-系 (hip-hop/street style) fashion magazine about 10 years ago, so I don't think they were sold commercially. I've only used them twice and they've been stored at home. The material is resin. They've been stored at home and there are no noticeable stains or scratches, but please understand that they are used, and consider purchasing them. #sunglasses #DOPE #sunglasses Lens Color...Black Frame Color...Black Lens Features...Non-prescription Stains, tears, odors, etc....None
