Simply draw the wire through the jaws, turn, and pull to complete the task. Utility pliers: These double nylon jaw pliers are ideal for straightening, twisting, and shaping jewelry wires and pins. The two large nylon covers on the flat heads help prevent jewelry threads from getting dirty or scratched. Widely applied: These carbon steel jewelry pliers are suitable not only for jewelry making but also for various craft and hobby projects. Enjoy your creative DIY experience with these versatile tools.
