The Wubbers Looping Pliers are designed to work with 20 or 22-gauge wire and will make identical round loops with an inside diameter of approximately 2.2mm. They are also the perfect tool for making your own eyepins and wire-wrapped beads. The instructional CD, included with each pair, gives basic step-by-step instructions that anyone can master in no time. The Wubbers Looping Pliers measure 5 ½" in length, feature carefully rounded jaws to prevent marring and are shaped to support your wire as you wrap, keeping your work straight. Looping pliers are supplied with an instructional CD.
