<p>The modular elements are used for constructing toy figures and are moulded from plastics in a range of geometrical shapes including a cube, a sphere and a triangular prism. These are provided with a combination of cylindrical projections and flat-bottomed blind recesses, enabling the elements to be joined together to simulate various positions. Straight rods are also provided, together with cylindrical right hand sections. These have similar projections and recesses, with some of the former provided with spherical ends to form joints. A flat circular disc is also used, having a central hole and no projections.</p> |
