The transparent Delphi has smaller pegs and closer holes than the Olympus and Olympus-Lite. Accordingly, designs made on the Delphi are smaller and more delicate. This is a great addition to the Olympus jigs since it facilitates making matching sets of jewelry. For example, smaller earring components can be made on the Delphi to match larger necklace/bracelet links made on the Olympus. It also works very well for paper arts designs.Includes jig with 181 holes, 20 metal pegs (1/16" diameter), and wire designing tips (wire, Super Pegs and nylon spacers are sold separately). The WigJig Delphi is patented (US Patent 6,253,798). The WigJig Delphi Jig is 3" x 3".
