This is a belt loop key holder, entirely handmade using oil leather. The leather used is Chromexcel from Horween. This leather is a "dye-on-the-surface" tea-core leather, meaning only the surface of the leather is dyed. Therefore, the aging process allows you to enjoy the unique characteristics of tea-core leather, such as the underlying color subtly showing through with use, or the base color becoming visible from deep scratches. Size: Approximately 17.5cm x 2.8cm (Leather part only when extended) (Leather thickness: approximately 2.6mm) Leather: Chromexcel (Horween) Tea-core Black Thread: Polyester (Rikka) Black Snap: Brass Jumper Snap Other Hardware: Brass *Please note that there may be some scratches during the manufacturing process, despite our careful attention. Also, due to the nature of natural leather, there may be wrinkles, tiger stripes, small scratches, and blood vessels. These are natural characteristics unique to genuine leather.
