This key hook is made with Chromexcel leather from the renowned American tannery, Horween, featuring powerful double rivets and a rugged 4mm diameter D-ring (also known as a belt loop). A one-star stud is used as a design accent. Large rivets are used, making it not only rugged but also a tough and durable key loop. Many people who love work boots or riders jackets are drawn to Chromexcel leather. Starting from the pattern, I kept searching for the right shape, a D-ring (attachment hardware) with a thick wire diameter, and studs that matched the image, and finally, it took shape. It goes perfectly with denim, leather pants, and leather jackets, and of course, with vintage clothing. It's also great for street fashion and rude styles. It looks cool paired with boots like White's, Wesco, and Red Wing, and it also goes perfectly with trucker wallets and wallet chains. This is a handmade item. The color is black. It's a "tea core" leather, which is dyed on the surface only, with a black surface and a brown cross-section and back, favored by those who love American casual and vintage styles. To show the brown side in a balanced way and to add a touch of elegance to the ruggedness, the edges have been beveled, and the edges and the flesh side have been treated. Everything was made with great care. While using a hook makes it easy to attach and detach, it deteriorates quickly with repeated use, so I opted for rivets. It's also recommended for bikers. A famous American brand known for its silver accessories also has rivet-style items. If you want to hang keys that you frequently remove, I recommend a separate key hook. The generous amount of beeswax and oil content allows for aging. It's an item that becomes more familiar and develops character the more you use it. 【Size】 Leather part length: approx. 7cm Width: approx. 3cm at the widest, 2.5cm at the narrowest (Compatible with up to 4.5cm width) Ring size: width 3.4cm, height 2.5cm Since new packaging is used, it's also perfect for gifts.
