This is a die for a coin case wallet. It's a cute coin case. It's easy to make, just fold and overlap, then fasten with snap buttons, with no need to sew. Ideally, you would use a press machine, but if you don't have one, you can also cut it out by tapping. Place the leather on the die and tap it with a rubber mallet or wooden mallet. The blade is sharp, so please be careful not to touch it.
