Molymod PS Polystyrene Polymer Kit (Each)

Molymod inorganic kits contain a sufficient quantity of molymod atom parts and links to make individual structures, e.g. sodium chloride, diamond, ice or metals. The kits are supplied in plastic boxes with assembly instructions. Some substances e.g. calcite, are only supplied as pre-assembled models. The models are of two kinds, either OPEN models which use standard grey links to give extended structures, or COMPACT models which use short links and bring the atoms close together giving a semi-space filling type of model.
