'Jurassic Sand Fossil' is a set of sand moulds that makes no towers and no sandcastles, but bones. The blue plastic moulds carry the profile of a dinosaur skeleton: a stretch of spine with ribs, a skull and a claw-shaped piece.
It works like any sand mould, which means it works straight away: damp sand in, press it down well, turn it over and lift carefully. The difference is in what comes out. Lay the pieces beside one another in the right order and a whole skeleton takes shape in the sand - which is exactly the point of a sand fossil.
It works as well in the sandpit as at the seaside. The moulds are supplied in a mesh bag with a hanging tab, so after playing they simply go back in.
You buy one mesh bag of moulds. The current product photo shows the counter display in which the bags stand together; that is not what is in your parcel.
