Keyholder made with black Tochigi Leather vegetable-tanned leather (single piece of cowhide). Handmade. Offered at the Mercari minimum price of 300 yen. After numerous prototypes, I refined the size and design down to the millimeter, pursuing a minimalist and simple aesthetic. Something that seems like it should exist, but doesn't. Simple yet impactful. That's the concept behind this creation. Perfect for small keys like bicycle keys, motorcycle keys, locker keys, and desk keys. Of course, it works for car keys too. I also paid attention to the size of the key ring, opting for the smallest possible ring, assuming it would hold a single key. The leather develops character with use, but being natural vegetable-tanned leather, there may be wrinkles called "tiger stripes" and minor scratches. While favored in the West, 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. Please refrain from purchasing if you are looking for manufacturer-like quality or are overly sensitive to imperfections. While the dimensions and materials are the same, the product may differ from the photos. Please understand this beforehand. Will be shipped promptly via standard mail.
