Ray-Ban sunglasses, featuring a double bridge and flat lenses. Ray-Ban Boston Double Bridge Flat Lens RB3647N 90683F 51 Purchased about 3 years ago and worn a couple of times, but I started using other sunglasses and have kept these stored at home with the case. The lenses are as they were when purchased, and have the Ray-Ban engraving. Includes the original lens cloth (unused) and the original case. The outer box is old, but I will include it as well. Everything is shown in the fourth photo. There are no noticeable scratches or stains, but please understand that these are used items before purchasing.
