While most eyewear frames are made of plastic and have a seam all around the edges from the injection mold, our sunglasses are made from blocks of cellulose acetate or horn that are carved into their final shape. This process gives the frames greater flexibility, durability, and depth of color.
Horn frames are available in dark color horn and light color horn. Horns are harvested from water buffaloes that reach the end of their working age, and are never killed solely for their horn. As every horn varies in color, each piece has a unique appearance.
