These are round glasses made of titanium from Hakusan Megane. They have prescription lenses, so please replace them before use. I bought them about 7-8 years ago and used them for less than a year, after which they were stored in a drawer. I think they are easy to wear because of their simple design. The original glasses case and cleaning cloth are not included. Please understand that these are used items. #HakusanMegane Color: Gray Frame material: Metal
