You will receive extruder discs made of PLA to make the motif shown from soap dough (or clay, polymer clay or other modeling pastes).

PLA is a plastic made from corn flour that is stable up to 65 degrees Celsius.
Too high temperatures and too much contact with water can damage it, so wash the extruder disks with lukewarm water and a sponge or brush; they are not dishwasher-safe.
