Air Dry Modeling Clay--no crack
Our air dry clay is soft and have good extensibility to make craft. There will be no crack after drying. The air clay will be hard on surface to keep outward appearance, and it will be lighter after drying.
The surface usually take 10-24 hours to harden. The inner will take more time to dry.
No bake and sealed storage the rest for next use. (usually can keep more than 3 months in this package).
