Introducing Ref Sunglasses - made from 100% biodegradable cellulose acetate. This is an oversized, square fame with rounded edges. Our sunglasses are made out of 100% cellulose (a fancy way of saying plant-based) acetate sourced from Italy. About 8 million metric tons of plastic are thrown into the ocean each year, these sunglasses won't ever be part of it. We know this is a drop in the ocean, but we can all do our part to help clean up.
