This is a tool for making covered buttons for handmade crafts, leathercraft, etc. It supports beautiful gathering by cutting thin leather with the included leather punch and pressing it into a mold of the corresponding size. In addition, all four corners can be used as corner gauges (R8, R12, R15, R20), making this a great value product. Made of sturdy brass, you can use it for a long time. Of course, it can also be made with materials other than leather. ◎Material Brass ◎Sizes ・Mold Sizes 9mm 10mm 12.5mm 15mm ・Punch Sizes 18mm 20mm 23mm 27mm I also have other leathercraft supplies for sale.
