Chanel Chopper to Bown Rimless Sunglasses

100% authentic and very rare vintage Chanel brown rimless sunglasses - 4048 185/59 Chopper to Bown model. Sunglasses are in amazing condition overall, some minor scratches on the right eye lens which I tried to capture in the photo. The case, however, is in poor condition. It is the original authentic case when these were purchased in I believe 1996/1997.
