This is a belt loop key holder, entirely handmade using Italian leather. The leather used is horse butt from GUIDI. This leather is vegetable-tanned, dye-finished leather from the horse's butt, an area with high fiber density. While the leather is dyed through and through, the area near the cordovan layer is typically not dyed on the back, which gives it a unique look. It's about 3.0mm thick but has a supple texture due to the oil content. Size: Approximately 17.5cm x 2.9cm (Leather part only when extended) Leather: Horse butt (GUIDI) Black (Leather thickness: Approximately 3.1mm) Thread: Polyester (Rikka) Black (color) Snap: Brass Jumper Snap Other hardware: Brass *Please note that there may be some scratches during the manufacturing process. Also, due to the nature of natural leather, there may be wrinkles, tiger stripes, minor scratches, and blood vessels. These are natural characteristics unique to genuine leather. We appreciate your understanding before considering a purchase.
