Thank you for viewing. This is a small leathercraft stamp set. You can insert the heads (alphanumeric characters) into the tip of the stamping tool and stamp with a hammer. You can easily stamp by simply changing the heads. [Details] ・Alphabet: A to Z (26 pieces total) ・Numbers: 0 to 9 (10 pieces total) ・1 stamping tool Character size: Approximately 4mm high x 4mm wide ※ A dedicated case is included, but There are dents, damage, and some dirt. There is no problem with the stamps themselves, but please refrain from purchasing if you are concerned. I used it for wedding invitations, but I don't think I'll be using it again, so I'm putting it up for sale. Thank you.
