The Om Tara Dual Crimping Pliers make the crimping process easier and more efficient. They help support the artist’s creative process rather than inhibit it. It is an easy, one-step process to achieve a secure crimp which can then be left as is, folded or flattened, or covered with a crimp cover. The smaller notch is for use with 1 to 2 mm crimps. The larger notch is for 3 to 4 mm size crimps.
