Extra-Large Ball Tool (T-004) is 7 1/4 inches (185 mm) long, and has a polished hardwood handle and chrome-plated ball bearings at each end that measure 25/32 inch (20 mm) and 21/32 inch (17 mm) in diameter. The heft of this tool and the generous size of its ball bearings make T-004 an excellent choice for working large petals without creating ridges at the edge. Overall, it traces broad, gentle impressions in any sugar medium.
