Keyholder made from black Tochigi Leather nubuck leather (single piece of cowhide). Handmade. After numerous prototypes, we refined the size and design down to the millimeter, achieving a minimalist and simple aesthetic. It's something you don't often see. Simple yet impactful. That's the concept behind this product. Perfect for small keys like bicycle keys, motorcycle keys, locker keys, and desk keys. Of course, it also works for car keys. We paid close attention to the size of the key ring, opting for the smallest possible ring, assuming only one key will be attached. The leather develops character with use, but as it is natural nubuck leather, there may be wrinkles called "tiger stripes" and minor scratches. While popular in Europe and America, more and more people in Japan are appreciating these as unique characteristics. 【Size】 Length: Approximately 5.5cm Thickness: 1.2cm Ring Size: Outer diameter 1.5cm Will be packaged in a new envelope. Perfect for gifts. Handmade product. Please refrain from purchasing if you are looking for manufacturer-like quality or are overly sensitive to imperfections. Although the dimensions and materials are the same, the product may differ from the photos. Please understand this beforehand. We will ship promptly via standard mail.
