Bring creativity, engineering, and racing excitement together with the MT4 Magnetic Track Building Set. This 91-piece STEM construction toy uses 360-degree magnetic track connections and snap-fit building pieces so kids can create flexible 3D layouts with horizontal and vertical structures, elevated pathways, loops, ramps, bridges, and crossover designs. The included Type-C rechargeable motorized race car travels through curves, ramps, elevated sections, and loop-the-loop tracks for interactive screen-free play. A flip bridge can swing between track sections to connect different routes and create new racing paths, while support brackets help stabilize taller structures. Designed for ages 3 and up, MT4 encourages creativity, spatial reasoning, problem-solving, hand-eye coordination, and exploration of motion, balance, gravity, and magnetic connections. | Contixo | | MT4 Magnetic Track 91-Piece 3D Building Set with Rechargeable Motorized Race Car, Ages 3+ | Best Buy
