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 Star of David stud is used as an accent in the design. Large rivets are used, making this a tough and robust key loop with a rugged feel. 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 (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 also looks great with vintage clothing. It's suitable for street fashion and rude styles. It looks cool paired with boots like White's, Wesco, and Red Wing, and also goes great with trucker wallets and wallet chains. This is a handmade item. The color is black. It's a "tea core" leather, which is a type of leather that is dyed on the surface only, with a black surface and brown edges and back, favored by 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 flesh side have been treated. Everything has been made with great care. While using a hook makes it easy to attach and detach, it deteriorates quickly with repeated use, so rivets were chosen instead. 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 are frequently removed, a separate key hook is recommended. 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: approx. 7cm Width: Max. approx. 3cm, Min. 2.5cm (Compatible with up to 4.5cm width) Ring size: Width 3.4cm, Height 2.5cm New packaging is used, making it perfect for gifts.
