It's Koi Because...
They throw serious shade. Fak by Fak's Limited Edition Black Mantis sunglasses are based on a feminine cat-eye shape transformed into aggressive unisex shades. The out-there shape is inspired by the allure and menacing appearance of insects in old sci-fi films and they are crafted from jungle camouflage frames and green brown tinted lenses.
