There is no safer place for top secret messages, a key or a valuable treasure. The Die drei ??? Geheimversteck is hidden on the underside of a stone made of air-drying modelling clay. Before the detective game begins, young detectives aged 8 and over make their very own hiding place themselves: the children press the modelling clay onto a mould and model the stone as realistically as possible. This way it remains inconspicuously hidden from prying eyes in the children's room or garden. Simply follow the clear instructions that show how to work the stone with the modelling tool and close the secret compartment. Justus, Peter and Bob would be thrilled: This hiding place is guaranteed to find no one.
