Koh-i-noor Keraplast Air Drying Clay is soft and easy to use. Just spray or mix it with water to keep it moist and pliable. Mould it, sculpt it or use modelling tools to add details. When done, expose it to air and it will harden - no need to fire in a kiln. You can paint over it using any acrylic paint. This 300g block of Kera Plast is wrapped in aluminium foil and available in White or Terracotta.
