This keyholder is made from soft, vibrant blue cowhide leather (single piece). Limited edition, limited color. Handmade. It uses a bright blue leather that's not often seen. The leather has a subtle sheen and a good thickness, giving it a smooth feel. We made numerous prototypes, refining the size and design down to the millimeter until we were satisfied, achieving a minimalist and simple design. 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, using the smallest possible ring, assuming only one key will be attached. Recommended for those who like brands like Comme des Garçons, Yohji Yamamoto, Issey Miyake, Margiela, Maison Kitsune, and CLANE. Made from genuine cowhide leather, it will become more familiar and take on your own unique color the more you use it. 【Size】 Length: Approximately 5.5cm Thickness: 1.2cm Ring Size: Outer diameter 1.5cm It will be packaged in a new envelope. Perfect for gifts. Handmade. Please refrain from purchasing if you are looking for the quality of a mass-produced product or are overly concerned with minor details. Dimensions and materials are the same, but the product may differ from the photos. Please understand this beforehand. We will ship quickly via standard mail.
