This key case is made from domestic saddle leather, simply crafted from a single piece of leather. If you like brands like slow or Il Bisonte, you might like this. The keys are secured to a 20mm inner diameter double ring, preventing them from falling out. Because it doesn't have a complex mechanism, it becomes more compact than you might think as the leather breaks in. Material: 2.2mm thick domestic saddle leather Closed size: Height 10cm, Width 4.5cm Ring inner diameter: 20mm The flesh side and edges are burnished with CMC for a natural finish. You can enjoy the unique aging of saddle leather and customize it to your liking. As this is handmade by an individual, there may be scratches, natural markings, blood vessels, and small spots. Please refrain from purchasing if you are sensitive to these imperfections. Shipped via Yu-packet. #TochigiLeather #NumeLeather #SaddleLeather
