The Ignis CMY Tetrahedron is a beautiful polyhedron composed of four triangular faces, six straight edges, and four vertex corners. The Tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces. It is one of the 5 Platonic solids. Rotate it just right and colours blend, the light catches the shape and merges colour with colour. In a darkened room, hold it up before light to project a magical spectrum of colour onto your walls and furniture; or place it in a sunbeam to illuminate your day – and steal the show. How many colours can you create? Designed in Australia. This item is in very high demand! Your order will ship out ASAP.  Sizes: Mini: 30mm  Original: 50mm
