These frames are made from cellulose acetate. This is a natural material, and very durable. The frames are cut from plaques of dyed acetate, and are then polished and hand-finished to superb standards. Unlike most plastics, acetate's pigments are an intrinsic part of the material, never losing their intensity. It makes a beautifully finished, high quality frame that will last.
