Thank you for visiting. This item uses horse leather. Unlike cowhide, it's about 2.5mm thick but has elasticity. Even without a gusset, it's easy to take out coins. It's the perfect size for a small coin case. We have many other new items, so please search for #8cloud. #8cloud #handmade #handsewn #genuineleather #horseleather #antique #coin case #wallet #oneofakind #repairmaintenancepage
