Create incredible figures with these special magnetic pieces. Each piece has multiple magnets with a unique design that allow them to connect strongly in any direction without repelling. This system was invented by a Japanese math teacher who wanted to create a better practical experience for learning geometry. The construction possibilities are endless, allowing minis to create without limits and very easily. The translucent pieces add a plus to the game, creating reflections of light, and can be used on a light table. It is also made with polycarbonate, a very resistant and durable material, the same material used for bulletproof glass, where magnets cannot come out. It is a perfect toy to develop motor skills, fine motor skills and the development of creativity, while also intuitively learning mathematics and geometry.
