The 3D Bracelet Jig is the perfect tool to make adjustable bangle bracelets. After you form the bracelet shape, use the Sizer Drums to reduce it to the correct bracelet size. Use the large drum 50.8 mm (2 in) with dead soft wires like Artistic Wire and the small drum 41.3 mm (1 5/8 in) with half-hard German Style or Sterling Wires.
