This is an auxiliary tool for using metal stamps in leathercraft. (Stamps are not included) The material is acrylic. You can use it if the stamp itself is 20mm or longer. (The general length is about 23mm) The width for the characters is a maximum of 44mm. It is for a single line of text. When setting the stamp, I made a backing plate, so you can set the stamp without it shifting by holding it down and tightening the screws. I also added a scale so you can easily find the center and stamp the leather. Not suitable for stamping by hand. Please use a press machine or clamp to apply pressure. Feel free to contact me if you have any questions.
