Classic sunglasses with a twist: The frame of these glasses are made from plastic mixed with wheat straw. Wheat straw is the stalk left over after wheat grains are harvested. Traditionally it has been treated as waste, but now it can be used in combination with traditional plastic. This reduces the quantity of plastic needed to produce an item and accelerates its biodegradability once it is eventually disposed of. The frame has a matte finish with a slightly speckled texture from the wheat straw. The arms are made from natural bamboo and these sunglasses are supplied in a 100% natural cotton pouch. pouch: 18 ( l ) x 9.7 ( w ) cm wheat straw material, bamboo & 100% cotton UV400 protection lenses
