We design premium accessories made for tech. We use full-grain leather from Scandinavia for a range of our products. This signature leather is well known for its exceptional quality. We also use 100% natural wool felt sourced in Germany as a lining material for several products. It is soft to the touch, with great shock-absorbent properties. Next to leather, we work hard to introduce future-oriented materials with a strong sustainability and tech focus. These synthetic materials include matte waterproof PU (free from PVC and PFC) as well as 100% recycled polyester deriving from PET bottles. The waterproof matte finish of the PU gives the products a timeless, yet contemporary and tech-like aesthetic in line with our product vision.
