If you do work on a pottery wheel, Speedball Bats are an absolute must-have in your shop or studio. Made from injection-molded plastic, these bats feature a rim that allows you to lift them from the wheel in one easy motion, leaving your work completely undisturbed. Special ribs give them added strength and stability. They can be used with all pottery wheels and are one of the best values out there for ceramicists. Made in the USA.
