Outerknown discovered OTIS's Eco-Acetate series recently and we haven't taken them off. Might be the handmade frames, Mineral Glass lenses, or stainless steel hinges. Might just be their good looks.
Mineral Glass is made from natural elements like sand and soda ash. It's scratch-resistant and endlessly recyclable.
Eco-Acetate is made from raw materials derived from cotton seed and wood pulp. 100% recyclable and 100% biodegradable.
Comes in plastic-free packaging.
