This construction vehicle set includes a crane truck, dump truck, cement mixer truck, and lift truck. The package also contains small worker figures with movable joints to create realistic construction play scenarios. The inertia-powered vehicles glide smoothly without batteries when pushed, encouraging active play. The moving parts and interactive elements help develop hand-eye coordination and fine motor skills in young children. Sharing the four vehicles with others can also support social development. Made with smooth, burr-free edges and durable materials, these trucks withstand regular play. Their compact size fits comfortably in small hands and makes them portable for travel. This set serves as a practical gift option for occasions like birthdays or Children's Day.
