Wire Twister tool is made of steel with a 4mm (0.15in) thick plastic disc. Place up to 5 Wires onto the disc of the Wire Twister, then attach the wires to a sturdy object. Pull the wires taut, turn the crank, and watch the wires twist. Use color combinations to create great looking Jump Rings. Multiple wires, once twisted, have more strength than single wires. Makes creating wire designs more interesting and fun.
