Black Chanel quilted sunglasses

Black quilted Chanel sunglasses. The lenses are dark grey, square shaped. From the left arm: 5124 c. 501/87 59o17 135 3N. The right lens has a mark where the left arm rubs against the lens when folded, but this doesn’t get in the way of vision when on. Otherwise I have kept them in good used condition. No case.
