FLASH SALE authentic prada blue matte sunglasses

got these for christmas, and i like them, but i've had my eye on some vintage-y ray-bans and i'd rather have them. SO really, the only thing i would trade these for is some RB3447s in gold! comes with a derek lam case bc the place they were purchased from, nm last call, ran out of prada cases. you can call and check!
