Eco-silk is an environmentally conscious code. Large quantities of silk are discarded in the manufacturing process at the factory. Eco-Silk is the one that collected that silk and made it into a new cord. The texture is rather like a cotton material, surprising for its casual feel, but it maintains the rich absorbency of silk. This product is a functional product that can also be used as a bracelet when the rubber parts on the tip is removed. The square part with the logo can be moved, and when used as a glass code, it is connected to the position of the shoulder so that it is comfortable to attach. When used as a bracelet, it becomes an accent of the design by putting two together.
