This tough, two-piece tractor-trailer is ready to roll . . . and ready to build! Packed with wooden construction pieces and pre-drilled with holes for the wooden nails and bolts, the truck itself is a moving building site. Connect the painted building boards to create brightly colored structures on wheels! The 22 wooden pieces, including a hammer, screwdriver, wrench, board, nails, nuts and bolts, store away inside the trailer to keep your little builder's supplies organized for the next big job. Big Rig Building Set is great for fine motor skills, hand-eye coordination and problem solving, and encourages imaginative play and manual dexterity. Country of Origin: Imported
