This is a genuine coin case die. You can cut with this die, sew it together, and attach a snap button. It's easy to make!!! Ideally, you would use a press machine, but if you don't have one, you can also cut it by tapping. Place the leather on top of the die. Try tapping it with a rubber mallet or a wooden mallet. Be careful not to touch the blade as the cutting edge is sharp. Paper pattern... other paper patterns
