Bring building to life with this two-piece rolling car pack — two vibrant motion bases with real rubber wheels (one blue, one yellow) that click under magnetic tiles to create mobile vehicles and moving structures. Designed for open-ended play and STEAM exploration, the set encourages imaginative vehicle-design, experimentation with motion and force, and cooperative play. Safe, sturdy construction (non-toxic ABS, BPA- and phthalate-free, ultrasonically sealed and riveted) makes it suitable for little builders; the pack includes one blue and one yellow motion base and is compatible with standard magnetic tile collections for easy expansion. Perfect as an add-on to a starter set — ages 3+.
