Geomag Pro-L is the evolution of the original Geomag magnetic construction system. Designed for those who love a challenge, the Pro-L line allows you to create more complex models and structures thanks to the greater strength of the magnets. We have built-in visible polarity indicators on each rod, which means you can grasp the full potential of magnetism and build more quickly, pushing the boundaries of the laws of physics. Comes with 75 pieces. Suits ages 8 years +. Features: An advanced version of the original Geomag magnetic construction system Ideal for those who enjoy challenging construction tasks Enhanced magnetic strength for creating more complex structures Visible polarity markers on each rod for better control and understanding Designed to enable quicker construction by optimizing magnetic potential Allows the creation of more intricate and sophisticated models Includes 75 pieces in the set Suitable for ages 8 and above Specifications: Dimensions: H:30.0 x W:40.0 x D:23.7 c
