This key hook is made with Chromexcel leather from the renowned American tannery, Horween, featuring powerful double rivets and a rugged D-ring with a 4mm wire diameter. (Also known as a belt loop.) A one-star stud is used as a design accent. Large rivets are used, making this key loop not only rugged but also tough and durable. Many people who love work boots or riders jackets are likely to admire Chromexcel leather. Starting from the pattern, I kept searching for a shape that matched the image, a D-ring (mounting hardware) with a thick wire diameter, and studs, 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 dyed leather, so only the surface is black, and the cross-section and back are brown. This is the so-called "brown core" leather, which is popular among those who like American casual and vintage styles. To show the brown surface 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. I was particular about everything. While using a hook makes it easy to attach and detach, it deteriorates quickly with repeated use, so I chose to use rivets. It is also recommended for bikers. A famous American brand known for its silver accessories also has rivet-spec items. If you want to hang keys that are frequently removed, 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: Approximately 7cm Width: Maximum approximately 3cm, Minimum 2.5cm (Compatible with widths up to 4.5cm) Ring size: Width 3.4cm, Height 2.5cm Since new packaging is used, it is also perfect for gifts.
