Created in collaboration with potter Jennifer Whilden, the Speedball Boss Ribs Clay Centering Kit is designed to make centering and shaping clay on the wheel more accessible for every skill level. The kit includes four rib sizes—two with strap loops for added control and two traditional—plus adjustable straps to customize the fit. The ribs are firm yet flexible for optimal performance during throwing and compressions, and the ergonomic design helps reduce fatigue during long sessions.
