Similar in principle to plasticine, this non-drying modelling clay from Scola is available in 20 single colours & 3 amalgamated blocks (neon, rainbow & skin). Exceedingly malleable, each block can be pulled apart, mashed together and reshaped again & again. Once shaped, it easily holds it's new form, remaining soft enough to be moved incrementally for stop-motion animation whilst sturdy enough to be an ideal method of making moulds for plaster casting.
