WILTON-Tilt N Mix: 3 pc Mixing Bowl Set. These bowls are not like any other mixing bowl you have seen before! These bowls have a series of five rubber feet on the bottom that serve two purposes: they will not slide around on the counter while you mix the contents; and they allow the bowl to be tipped on an angle allowing for better access to what is inside while mixing or scooping. Bowls are top-rack dishwasher safe. Bowls are constructed of heavy duty white plastic with yellow rubber feet. Sizes in set: 1-1/2; 3; and 5 quart. Imported.
