Self-hardening modeling paste MUNGYO Sculpt Dry from the Air Dry Clay series is a ready-to-use natural product, identical in quality to clay. However, it is much easier to work with, as the paste is easy to mold, requires no thermal... treatment, and hardens in the air within 24 hours. It rolls out easily and cuts well. It dries naturally in the air (within 24 hours) without the need for firing. After drying, the crafted item is very sturdy and does not crack. It can be sanded well. It is perfect for doll-making - well-kneaded clay adheres to the other body parts of the doll without seams; it smooths out easily.
