406mobthose are fake rayban doesn't put stickers on the lens
I think you bought fake ones then. They do put a gold foil sticker on the lens. However, telling if these are real or not is nearly impossible without seeing them in person or without a receipt. The case looks right and the glasses look right, but, it's easy to fake black ones especially.
Seller, since you have a low post count, you're going to have to prove how you acquired them from a legitimate seller.
