The VARIO piercing tools are the perfect compliment to the Prym VARIO pliers for non-sew products and are suitable for fabrics, leather, foils etc. As the 3 Prym tools have diameters of 3, 4 and 8 mm, this allows a lot of flexibility when punching the holes you need. For thin materials a cardboard sheet should be placed anderneath. Includes a replacement lever for easy removal of the tools from the pliers. When not in use the pliers can be held together with the lever. Each pack contains two spare plastic inserts.
