Polymer clay is a sculptable material based on the polymer polyvinyl chloride (PVC). It usually contains no clay minerals, and is only called "clay" because its texture and working properties resemble those of mineral clay. It is sold in craft, hobby, and art stores, and is used by artists, hobbyists, and children for making many items, such as charms, artwork and other crafts.
Polymer clay sculpting is one of my hobbies and also my source of income. I make little things out of polymer clay and sell them online.
