The peace sign became famous during the 60's peace movement. The pendant is cast 316L recycled stainless steel (min 60% post consumer content) with a matte finish. The polycord comes from recycled PET bottles and industrial fleece scrap, is super durable, comfortably soft and dries quickly. You never have to take it off. Wear it swimming or in the shower. Cord comes long and is easily trimmed to just the length you like. Pendant is 21 mm in diameter - about the size of a quarter.
