Sustainable key case that manages multiple keys at once

Master-piece, which started in 1994, offers made-in-Japan bags that combine utilitarian design and functionality at a high level. Using functional materials and original parts selected from Japan and abroad with a focus on strength, water repellency, and lightness, the product is characterized by its coloring, which is a combination of different materials. The more you use it, the more you will feel the attention to detail. The Notch series smart key case uses carefully selected original parts despite its small body. The point is that it is compact and fits in the palm of your hand, so it fits easily in your bag. Comes with 3 eggplants and a carabiner, allowing you to carry multiple keys at once. The deep, lustrous leather is made by the only tanner in Japan that has obtained LWG (Leather Working Group) certification. This is a sustainable key case that is also environmentally friendly.
