The easy crank handle makes this the ideal tool for the young, the elderly and anyone with wrist problems. The extruder works with all types of polymer and air dry clays and is ideal for making your own canes and embellishments. The wide variety of discs allow almost any shape to be extruded - from rounds and ovals to triangles and teardrop shapes. If you are a baker and using this for fondant ensure the tool is cleaned properly before and after each use. Do not use the same tool for clay that you use for food. Recommended age 14 and up.
