Wire Looping Pliers Our Wire Looping Pliers easily bend wire into jump rings, loops and coils. Three different sizes on the round jaw are used to form 2mm, 3mm, and 4mm loops, and the fully concave shape of the other jaw makes the rings uniformly round. Box joint construction, with PVC grips for maximum control and durability. Overall length: 5-1/2" Jaws: 1" Why do I need this item?
