These Ultimate Clay Extruder Discs are manufactured from high-grade stainless steel and intended for use with all types of modeling media.  Disc design patterns vary from the basic geometric shapes which are always popular for making borders and armatures to more complex disc designs required for making embellishments, canes and custom jewelry.  Combine two or more discs together to create a custom design pattern.  All Makin's extruder discs are designed to be interchangeable between any of the Makin's Ultimate Clay Extruders and/or ClayCore Adapters (see Related Products).
