The Magformers Basic 14 hone their problem-solving skills, whilst inspiring imagination. This magnetic construction set introduces great new shapes (squares with circle insides) and brings a great new dimension to any 3D structure made using Magformers. In this box there are two squares with circle inners, four squares and eight triangles. Children can make anything from a simple pyramid to a flower, mouse, dog - and a whole host of other shapes. 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.
