What do you get when you put a circle on a square? You get the RB3548N hexagonal model, the evolution of the round model with flat glass lenses. Flat lenses and round shape: when it comes to lenses, you can't add more. The hexagonal round metal frame features thin coined profiles and classic gold crystal flat lenses with very thin temples. Mix and match basic flash color options to create the perfect combination. Experience the thrill of wearing an updated classic that won't make you feel like a fish out of water.
