Silk clay modeling set - Basic colours 10 x 40 g. This Silk Clay® modelling clay set box is ideal for children's manual activity. Thanks to this clay, the youngest children (from 3 years old) will enjoy modelling, sculpting, creating 3D shapes or decorations. The clay can be applied to wood, polystyrene or other materials. The advantage of Silk Clay® modelling clay is that it is self-hardening, i.e. it hardens in the open air. As you will see, it is easy to use and the designs are easily attractive. Bring an original decoration into a child's room, on a garland or on objects. A great creative activity to do at a birthday party or on a rainy day. .
