With Air Dry Clay, children can feel like real sculptors with endless possibilities before them. The clay is ready for use and dries hard after one day. Once the clay dries, it can be painted with tempera or acrylic paints. Wetting hands prior to using the clay is recommended. Clay is dermatologically tested, safe and washable. Store in an airtight container when not in use. Recommended for ages 3 and up.
