Clayotic
Clayotic, also known as Mess Free Play Dough and No Mess Modeling clay, is a brand of non-toxic, air-hardened modelling clay sold by the Irish company of the same name. It is created for young children to sculpt figures like regular clay. Clayotic comes in several different colours which can be mixed to make others. Once Clayotic is exposed to air within 24 hours, it hardens and dries.
