The Magformers Basic Plus 30 magnetic construction set introduces a great new shape - squares with circle shaped inners. This brings a fab new dimension to any 3D structure made using Magformers. In this box there are 4 circles, 4 squares with circle inners, 12 squares and 10 triangles. Every piece contains strong neodymium magnets safely sealed in every edge, but because the magnets freely rotate, they always connect and never repel when two pieces are brought together. The set is compatible with all our other Magformers sets, so pieces can be combined with existing collections to make amazing structures. Children can make anything from a simple pyramid to a flower, mouse, dog, cube - and a whole host of other shapes. With an ideas booklet to encourage creativity, this original Magformers set has everything.
