Leathercraft Stamps Alphabet: A to Z, & Numbers: 1 to 9 (6 and 9 are the same) Comes with a dedicated case You can easily stamp by lightly tapping on wet vegetable-tanned leather with a hammer or similar tool. It seems you can also stamp on 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, there are also 3mm and 5mm sizes available. I also have other leathercraft supplies for sale. If you would like to purchase them together, I can discuss the price, so please take a look if you're interested. Leather tools are here ↓ #YLWorksLeatherTool #Handmade #Leathercraft #Leather #Tools
