I found this while cleaning out my parents' house. These are Ray-Ban sunglasses from around 2000. The engraving has worn off, so I'm not certain, but I think they're RB3183. They show overall signs of use, with a crack in the lens and some corrosion on the metal frame. They're perfect for Y2K fashion, but due to their condition, how about using them as disposables? No returns/no claims. Instant purchase OK. Thank you.
