Vintage gray clip-on sunglasses

Vintage & timeless clip-on sunglasses + black leather carrying case. The sunglasses have gray lenses; each lens measures 1.25 inches by 2 inches. The frame is a brassy matte gold color and looks like thin wire; the sunglasses measure 4.75 inches across. Adding these to regular glasses gives a quirky / boho aesthetic. The case has a few minor scuffs on it (see photos). The case measures 2.1 inches by 5.25 inches by .75 inches; secure, hinged enclosure and black velvet interior.
