Some say these are a myth. Some say they are a legend. I know they exist! The Vintage Cazal 634 Snakeskin Sunglasses are one of the rarest frames to find for many reasons. First off, Cazal USA was the only ones to distribute them. They were skinned in Canada with a factory that is no longer in business. Second, some of the Vintage Cazal 634 Snakeskin Sunglasses got ruined to do how delicate the skins are. I am lucky enough to have one in my collection, but rarely wear it do to how delicate it is! Thanks to all the Cazal Phanatics for the picture!
