The Wubbers Oval Mandrel Pliers are perfect for making your own small oval jump rings for securely linking jewelry components. They also create beautiful arcs. The wider side of the jaw forms gentle swoops while the narrower end of the jaws can create more pronounced arcs. The non-tapered jaws provide matching curves with perfect arcs each time without having to measure for consistency. The style of the handles makes these pliers easy to control and they are engineered to help prevent hand fatigue. All are 6.75 inches long except for the Jumbo size, which is 7 inches long.
