Using these jewelry keychain cases is super easy. Just open the case, place your jewelry inside, and close it. The swivel snap clip allows you to attach it to your bag or keychain for easy access. When traveling, you can keep all your small jewelry items organized in one place. As for maintenance, simply wipe the vegan leather with a soft, dry cloth if it gets dirty.
