This key hook is made with Chromexcel leather from the renowned American tannery, Horween, and features 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 this a tough and robust key loop with a rugged look. Many people who love work boots or riders' jackets are drawn to Chromexcel leather. Starting from the pattern, I searched for a shape that matched the image, a D-ring (attachment hardware) with a thick wire diameter, and studs, and finally, it took shape. It goes perfectly with denim, leather pants, and leather jackets, and also looks great with vintage clothing. It's suitable for street fashion and rude styles. It looks great paired with boots like White's, Wesco, and Red Wing, and 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 commonly known as "brown core" leather, which is popular among those who like 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 would make it easier to attach and detach, it would deteriorate faster with repeated use, so I opted for rivets. Recommended for bikers as well. 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 will become more familiar and develop character the more you use it. 【Size】 Leather part length: Approximately 7cm Width: Maximum approximately 3cm, Minimum 2.5cm (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.
