Blue Journey AW22 Eco-friendly Collection Our Eco-friendly glasses are made of 97% degradable materials - acetate. They are composed of fiber polymers in natural cotton seeds, which are decomposed into glucose and acetic acid under specific circumstances. After further degradation, new biomass raw materials will be formed in nature. In addition, we use as less metal material as possible for eyewear. And we'll select titanium with excellent corrosion resistance, mechanical properties, and process properties to improve the quality of our products so that they could reduce extra consumption.
