The Eco Perth is a classic beauty. This acetate, lightweight frame will add class to any outfit. Features include a keyhole bridge, spring hinges and Eco branding on the inside of the frame. Youll want to add this beautiful frame to your eyewear collection! Eco is the first and only optical and sunglass collection made with 95% recycled materials. Eco received an Environmental Claims Validation (ECV) from UL Environment (ULE), a wholly-owned subsidiary of Underwriters Laboratories (UL), a world leader in product evaluation. The ULE validation substantiates Eco’s assertion that the eyewear is made with 95 percent recycled stainless steel and plastic.
