These small round Super Pegs expand your wire designing possibilities when using transparent WigJigs. There is one Super Peg in each of six diameters (3/16", 1/4", 5/16", 3/8", 7/16" and 1/2"). These pegs fit the Olympus Lite. Super Pegs are an important accessory to our WigJig jewelry tools. They allow making a defined radius in jewelry wire. If you need to shape jewelry wire in a rounded shape with a diameter of 3/16" to 1/2" then this set is the one you need.
