Ray-Ban photochromic lens sunglasses. Model: ORB3548N Color: 9131OX These sunglasses use photochromic lenses that darken in response to ultraviolet light. Purchased in October 2021. Used a few times after purchase. I bought new sunglasses soon after, so I haven't used these much since then. I liked them, but I'm selling them. The blue color variation seems to have been worn by HYDE-san ^_^ Made in Italy Accessories: Case, manufacturer's warranty, instruction manual Lens Color: Pink Frame Color: Gold Stains, tears, odors, etc.: None
