Makins Professional Ultimate Clay Extruder Clay Core Adaptor Sets give clayers expanded design options and flexibility to create geometric clay shapes with hollow cores built in.
This is particularly useful when making beads or bails.
This is the large sized set with 3.5mm, 4mm and 4.5mm adaptors.
For best results thoroughly condition modelling medium to achieve a malleable consistency. If the clay is too hard, this will damage your extruder.
