The Small Square Mandrels can add distinctiveness to your designs by forming small square jump rings or square-shaped hollow tubes and beads. The different-sized jaws add to their appeal by providing two sizes of squares in one tool. Handling up to 16-gauge wire and 24-gauge dead soft sheet metal, these are deceptively tough. Their wide shoulders provide powerful leverage to ensure that the tool does all the work. They are comfortable for even the most arthritic hands to use, due to their unique design and padded handles.
