The white Silk Clay modelling clay from Creativ Company in a large 650g pack offers creative fun for the whole family. This extremely light, smooth and air-drying clay is effortless to shape, roll and model without sticking to the hands or leaving residues. It hardens at room temperature within 2 to 24 hours and retains a rubbery, soft consistency afterwards. Supplied in a practical, airtight bucket, the modelling clay stays fresh for a long time. Should it ever dry out slightly, its elasticity can easily be restored by kneading it with a little water.
