With the Wonder Makers design system Special Delivery Depot building set, kids can design and build their own post office, where they can slide packages down the mail chute, load them onto the truck, and send them out for delivery! Using the 35+ reconfigurable play pieces, preschoolers can mix and match different designs using the same pieces to make the building or connect into tracks for the vehicle. With so many combinations to explore, kids can make a different post office again and again—there's no wrong way to play! Where development comes into play Creativity & Imagination: Kids can let their imaginations run wild as they use creative thinking to design the post office and tell stories with the characters. Engineering & Building: As preschoolers build and re-build the post office, mixing and matching the play pieces to create different configurations, they'll practice their designing and building skills!
