This is a tassel strap die. I think it's a very convenient item. The tassel height is 40mm, a cute millimeter size. Size: Approximately 128mm x 40mm x 3mm Ideally, you would use a press machine, but if you don't have one, you can also punch it out by tapping. When tapping, it's better to use a rubber mallet or a mallet. Place the leather on top of the die and tap with a rubber mallet or wooden mallet. The blade is sharp, so please be careful not to touch the blade.
