The arms are the key to the endless style of these butterfly sunnies - along with the sumptuous color: four metallic chain links surrounded in plastic culminate in solid elegant curved earpieces. At the front, the frame widens slightly at the outer edges for a slightly mysterious look. Your order will include a variety of the five distinct color/lens combinations available in this style, including: black frames, arms, and earpieces with black gradient lenses; brown frames that lighten to basil green on the bottom inner edges, brown arms, and brown earpieces that lighten to basil green at the tips, and black gradient lenses; medium brown frames that lighten to rose pink on the bottom edges, brown arms, and brown earpieces that lighten to rose pink at the tips, and black gradient lenses; brown frames that lighten to gray on the bottom edges, brown arms, and brown earpieces that lighten to gray at the tips, and amber gradient lenses; and dark tortoiseshell frames, arms, and earpieces and amber gradient lenses. These sunglasses are sold wholesale by the dozen.
