These IZIPIZI Round Sunglasses style #M are an oversized style that are made of castor oil, a natural vegetable oil that’s produced from pressed castor seeds. In their ongoing effort toward sustainability, IZIPIZI chose this eco-friendly material that is not produced using non-renewable sources of energy. Conceived by a trio of designers from Lyon, France, who observed their parents' constant struggle to locate their readers, this line of chic, ready-to-wear sunglasses satisfies the need for fashionable outdoor readers at an accessible price. In a range of colors that run the gamut from classic to eye-catching, these stylish shades flatter all face shapes, have velvety, soft finishes, and have flex hinges for a universally snug and comfortable fit. Packaged in a felt pouch and case. Non-polarized. 100% UV Protection.
