I received another pair of sunglasses as a birthday present from a friend, so I don't think I've used these more than 10 times. They've been stored in a dark place and I'm selling them as they are. #I am also listing other beautiful items. These are open-frame sports sunglasses with smoke lenses for clear vision. - Color: Black - Style: Sports Sunglasses - Design Features: Open Frame Design - Lens Type: Smoke Lenses Thank you for looking.
