Product Description
The SlumpHump is a durable plastic mold which allows you to pour your own low-cost plaster molds quickly and easily. SlumpHump molds are available in fourteen popular shapes and sizes. The SlumpHump is reversible -- you can pour both a slump mold and a hump mold. Another advantage of the SlumpHump mold is its tapered wall, that lets you vary the depth of the mold simply by adding more or less plaster.
