■ Keyholder (Belt Loop Type) This belt loop keyholder is made with domestic leather (tanned with tannins). It's 3mm thick, making it relatively thick for a leather accessory. The D-ring uses brass parts. A thick D-ring with a wire diameter of 4mm is used, giving it a rugged overall finish. Made with full vegetable tannin tanning, you can enjoy the aging process along with the brass parts. The snap button is a durable jumper snap (antique-plated steel). ■ Materials Leather: Tanned leather Color: Black D-ring: Brass ■ Using Scrap Leather Since scrap leather is used, there may be healed scars (marks from injuries the cow received during its life), stains, and wrinkles. We appreciate your understanding. Also, as this is a handmade item, it does not have the precision of an industrial product. We hope you can enjoy that aspect as well.
