Handmade. Goat skin "goat leather" belt loop. This leather is excellent in tensile strength and abrasion resistance, so you can use it for a long time. You can attach a wallet chain, etc., by threading it through your belt. There are two places, so you can use one for a wallet chain and the other for keys, etc. It can be used with belts up to about 3.5cm wide. It's difficult to use with wider belts because the hardware will interfere.
