Connetix magnetic tiles encourage hands-on learning through imaginative, open-ended, STEAM-based play. Each tile has magnets ultrasonically sealed inside, allowing kids to snap them together as they build 2D and 3D creations. This 50-piece transport pack has all that kids need to create countless vehicle designs, including a reversible transport base and 2 motion bases with real rubber wheels. Kids can build upon the bases, then add tiles to make trucks, trains and anything else they might dream up.
