Thank you for viewing. ■ Key Ring (Belt Loop Type) This is a belt loop type key holder made of vegetable-tanned leather. The thickness is 3mm, which is relatively thick for a leather accessory. The ring part uses a 3mm diameter D-ring made of stainless steel, and the hook parts are also unified in silver. You can enjoy the aging of vegetable-tanned leather. ■ Materials Leather: Vegetable-tanned leather Color: Black Parts: Silver ■ Using Scrap Leather Since scrap leather is used, there may be scratches, stains, and wrinkles. We appreciate your understanding. Also, as this is a handmade product, it does not have the precision of an industrial product. We hope you will enjoy that aspect as well.
