This is a set of three A4-sized vegetable-tanned leather pieces. The thickness is approximately 2.3mm. This is natural leather that has not been processed with oil, saddle leather, or shrinking. The leather is firm. It's perfect for those who want to enjoy aging, and can also be used for stamping. This is a great deal with a large scrap set, so why not stock up?
