Stimulate developing minds and channel their creativity with the Geomag Pro-L 110-piece Construction Set. Your little engineer-in-the-making can connect and build architecturally sound structures like a bridge using assorted panels, magnetic rods, and non-magnetic steel balls. Or with a little imagination, they can build something more fantastical and abstract. Geomag Pro-L is the evolution of the classic magnetic construction system. The power of this special magnet allows you to build even more spectacular structures. The polarity indicator, which is shown on the rods, helps you to understand the full potential of magnetism.
