Ray-Ban Polarized Erika sunglasses

These are Ray-Ban's Erica style sunglasses. They are a dark and very subtle tortoise with a brown polarized lens. They come with the original case and cloth. They are new but there are no tags. I tried to photograph the ID information that's on the frame, but it's so thin that it was hard to take a picture of so in case you want it: RB 4171 ERIKA 710/T5 54 18 145 3P
