Use Mrs. Anderson's 7-Layer Cake Slicer to create cake layers of your desired thickness. The outer diameter expands and contracts to fit cakes with diameters ranging from 9 to 12 inches. Slice through every slot for thinner layers, or through every other slot for thicker layers. The solid section helps support cakes while slicing, and the double handles steady the slicer while slicing. Made from durable stainless steel. Dishwasher safe.
