This is an acrylic stamp sheet for use in leathercraft. Please refer to the image for the available English alphabet, numbers, and symbols. A wooden stamping stick is included. Place the sheet on moistened vegetable-tanned leather, place the stamping stick on top of the sheet, and then stamp with a mallet or similar tool. It's inexpensive and stamps surprisingly cleanly, so I recommend it. It's made of acrylic, so it will naturally deteriorate, but the cost performance is good. Regarding the size of the characters, it varies depending on the shape and length of the characters, so please consider the image's markings as "approximate." Thank you very much.
