Thickness, size, hardness, and leather type vary. This isn't vegetable-tanned leather, so stamping isn't possible. Hole punching isn't possible due to the quantity. Stamping and the use of parts like the reference image are possible. Some backs are rough. There are wrinkles. Leather scraps may be attached. Please brush them off before use. Items other than those in the images will also be included. #GenuineLeather #LeatherTags
