Add snap fasteners to your designs with the help of the snap die set. This set works with the crystal applicator handheld tool to attach snap fasteners to clothing, jewelry designs and more. The die set is compatible with snap fasteners and decorative buttons. There are two front pieces and two back pieces in the set. The back pieces are for attaching the back of the snap fastener and the front pieces are for attaching the front of the button. Only one set of pieces can be on the tool at a time. When attaching decorative buttons, you only need to use the two front pieces.
