First, we make small colored pellets of various hues of yellow, brown and orange by mixing organic color powder with raw biodegradable cellulose acetate. The result is a highly durable, hypoallergenic material, made from renewable resources. The colored acetate pellets are then mixed and stirred by hand to achieve our speckled Havana pattern, thus making the pattern on every frame unique - no two pairs alike. Monokel Forest Sunglasses
