Detailed description: The Clay Extruder is designed with metal clay artists in mind. The entire unit is made from clay-friendly stainless steel and comes with ten discs. This precision instrument is easy to operate and capable of creating geometric extrusions that in many cases would defy creation by current clay forming techniques. The discs are specifically sized to be appropriate for metal clay, though the extruder can also be used for polymer clay applications. The 10 stainless steel discs pictured are included!
