My First Explorers is a magnetic play set that seamlessly integrates into the SmartMax universe. Mix and match the car, plane, and rocket to create a unique set of vehicles and let your imagination soar. The different parts of the vehicles magnetically attach to a SmartMax bar. You can either build your vehicles around the regular bar or create an even longer version by using the long bar. My First Explorers sparks imagination, fine motor skills and encourages hand-eye coordination.
