Yes, your acetate glasses can also be organic if, like us, they are produced with mostly natural, renewable raw materials and are biodegradable. COBLENS converts all acetate eyewear production to Mazzuchelli's M49 bio-acetate. The natural polymer cellulose, which is processed into cellulose acetate, is combined with a plasticizer of plant origin. With every Bio-Acetat COBLENS you get glasses with high environmental compatibility, bio-based, without any loss of quality and high durability. Good for you and for the environment. The bio-acetate COBLENS is one of the most sustainable glasses that you can currently buy.
