For those fans of substance, this frame will not fold four different ways into a square the size of a Starburst. D28 is a hearty helping of precision-cut, 100% acetate with “Izquierda” and “Derecha” laser-etched across the top in case you forget which side is left and which is right. A premium hard coating protects lenses, increasing durability and minimizing scratches. Lenses include a high-performance water, dirt, and grease-repellent coating for easy maintenance and superior optics. Premium, bio-based acetate frame with 5-barrel industrial hinges.
