Leathercraft Stamps Alphabet: A-Z, & Numbers: 1-9 (6 and 9 are the same) Comes with a dedicated case You can easily stamp wet vegetable-tanned leather by lightly tapping with a hammer or similar tool. It seems you can also stamp wood and metal plates like dog tags. Besides leathercraft, you can also use them for making original accessories. Please refer to image 5 for the size and font. From top to bottom: 3mm, 4mm, 5mm. In addition to the 4mm stamp size, 3mm and 5mm sizes are also available. I also have other leathercraft supplies for sale.
