The Rhombus Lab keyring is designed for small yet practical uses. It can be easily twisted on and off, making it a handy tool for various needs. The keyring is made of stainless steel, designed to last and be cherished for years.

Over time, natural marks may develop on the surface, but these traces only enhance the material's inherent function and beauty. By embracing the natural colours and textures of metal in a harmonious design, Rhombus Lab offers a seamless integration of functionality and aesthetics, creating a refined everyday experience.
