This is amazing, both as a sensory product and as a modelling medium. You can use it and pop it back in containers or leave it out and it dries in the air. Fabulous for fine motor improvement, creativity and all round fun. When this comes out in our house the adults want at it as much as the kids.
We have stuck it to glass, made jewellery out of it, made dioramas using boxes, figurines, , Christmas decorations, decorated photo frames .... the options are endless
It is non toxic but not suitable for 3 and under.
