This ingenious tool can save you time and money by making consistent 1.5mm loops in 24 to 18 gauge wire. It also bends and trims wire stock. The patented interlocking loop mandrel works with bare wire stock or already-beaded wires. Trimming guide hole allows for loop-making right up to the edge of the beads. Heavy duty coiled spring hinge and ergonomic plastic handles help reduce hand fatigue. Take the guesswork out of making your own custom eye pins in dead soft or half hard precious metal wire, craft wire, and copper or brass core wire. Not for use with hard wires such as memory wire, flex wire, steel wire, or music wire. Back of product packaging shows basic instructions.
