This loop key holder is made with domestically-sourced Tochigi Leather (cowhide), known for its reliability and proven track record. The leather undergoes a full vegetable tanning process, using only natural ingredients. Compared to cheaper chrome tanning, which uses chemicals, this method allows for a beautiful, deep color that ages gracefully over time. The leather color is chocolate brown. Due to the natural materials, the color intensity may vary depending on the leather. The loop holder is 26mm wide and approximately 180mm long (excluding the hardware). When folded, it's about 85mm long. (All measurements are approximate.) It features a snap closure for easy removal. It can be attached to belts up to 45mm wide. The hardware is nickel-plated (silver color). (*1) Tanning with tannins generally results in a firm leather, as it tightens the fibers. However, with use, the fibers loosen, and the leather develops character and a unique patina. As a natural material processed from animal hide, the leather's surface may bear various marks from the animal's life. These marks, along with the overall texture of the leather, tell the animal's story and serve as proof that each leather product is one-of-a-kind. The belt in the fifth image is a reference product and is not included. Color: Brown
