No Brand Size Lens: 3.3cm x 5.5cm Front Width: 14.5cm Temple: 15cm Lens Color: Blue Gray Please note that there may be some errors due to amateur measurements. These are biker shades purchased about 30 years ago at BACKDROP in Shibuya. I don't see them much these days, but back then they were as popular as DEN's celluloid type. I don't remember the details of the brand, but even after 30 years, the frame is not distorted and is very durable, so I think it was ordered and sold by a domestic manufacturer. The temples are straight and designed for motorcyclists, allowing them to be easily put on and taken off while wearing a helmet. I think it's a beautiful item without major damage, but there may be fine scratches, so please refrain from purchasing if you are looking for a perfect item. As a bonus, I will include a Ray-Ban case. It can be stored in a just-right size. #BikerShades #Sunglasses #BACKDROP #SetagayaBase #RayBan #UsedClothing #Vintage #ChampionReverseWeave
