Create incredible figures with these special 3D magnetic pieces. Each piece has multiple magnets with an exclusive design that allow you to connect strongly in any direction without repellent. This system was invented by a Japanese mathematics teacher who wanted to create a better practical experience to learn geometry. The possibilities of construction are infinite, allowing the minis-how to create without limit and very simply. The translucent pieces add a plus to the game, creating light reflections, and being able to wear on a light table. It is also made with polycarbonate, a very resistant and durable material, the same material used for bulletproof glass, from which the magnets can not leave. It is a perfect toy to develop motor skills, fine psychomotive and development of creativity, while also learns intuitively mathematics and geometry. This set contains19 translucent forms: 4 square pyramids, 8 triangular prisms, 12 cubes, 2 hexagonal prism and 3 rectangular prisms. Each form measures approximately 2.5 x 2.5 cm. The box measures 20,32 x 4 x 20.32 cm. From 3 years.
