Basic who? Everybody loves a classic, but who says it can’t have a little spice? Sunglass 11 is our take on a classic square lens shape, but bigger and with all the right angles. The Mazzucchelli M49 cellulose acetate frame is fully plant-based, composed of materials like cotton seeds and wood fibers making it bio-based, 100% biodegradable and fully compostable. Combine that with CR39 lenses with UV400 protection, and you have a pair of protective, powerful and high-end sunglasses.
Frame size: 58mm x 14mm x 145mm
What does it mean if something is bio-based?
When a product is bio-based, it means that it comes from materials of natural and renewable origin, like cellulose acetate. Mazzucchelli for M49 comes from natural and renewable sources like wood, whose cultivation and harvest are managed according to the guidelines of the Forest Stewardship Council (FSC).
What is cellulose acetate?
Cellulose acetate is natural polymer. The acetate used for our sunglasses is combined with acetic anhydride and plasticizers of vegetable origin, creating a natural and high-quality frame.
Biodegradable? So, they will slowly come apart?
Nope! According to the International Organization for Standardization, the term biodegradable is used to define any material that can be broken down by the enzymatic activity of microorganisms, sunlight and other environmental physical agents, into simple chemical compounds. In order to define a plastic material as biodegradable, the degree of biodegradation must reach 90% in an incubation time of no more than 6 months.
