Use the design wheel to cut strips of fondant or to emboss patterns on fondant or gum paste. Three detachable wheels: straight, wavy, and ridged attach to the end of the handle. To cut strips, use the straight-edge cutting wheel and roll the wheel along a ruler to cut perfect strips. For embossing, attach one of the two patterned wheels and roll the wheel along the fondant in any direction. The wheels create great-looking dots or waves to give your fondant cake terrific texture. Set of 4: handle and 3 wheels
