Supplied as rolls measuring 3 metres long and 80mm wide. Young children should have adult supervision. Art Roc is a plaster and resin impregnated bandage strip that can used to make a variety of light structures or sculptures. Just wet the strip and drape it over wire, cardboard, bottles, balloons - even scrunched up newspaper - to make your model. You will need between 3 and 6 layers, overlapping and laying the strip in different directions. It is a very versatile modelling material and is ideal for making theatrical props.
