This is a key case from Kamito Kaban Seisakusho. The design is a common zipper type. The leather used is called crazy horse leather, which doesn't have a smooth surface but rather a slightly brushed, soft feel. Despite the name "crazy horse," it's cowhide. Crazy, isn't it? I bought it and realized the surface had a brushed texture, so I replaced it with a regular nubuck leather key case. Therefore, this one has been stored away with hardly any use. Color...Black系 (Black-based) Stains, tears, odors, etc....None
