The Beadsmith 7-Piece Mini Mandrel Set is the ideal tool to create a variety of different shapes with perfect consistency every time! The tools measure approximately 3.5 inches in length, and each tip is tapered, with the capability to create a multitude of different diameters. Made of carbon steel and sanded smooth, the surface will not mar wire- terrific for both beginners and seasoned designers who want to create professional-looking jewellery. The set includes 7 shapes: oval, square, drop, rectangle, triangle, heart, and star. To use: select the mandrel size that works for your project. Begin to wrap the wire, pulling it tightly as you wrap it around the mandrel to create your design. Continue wrapping the wire around the mandrel until you have what you need for your piece. To finish: remove the shaped wire from the mandrel and snip to create a multitude of consistently shaped wires! When you're done working on a project, everything stores nicely in a plastic container.
