It's time to get constructive fun rolling with these sturdy wooden vehicles. The eight-piece set includes a steam roller, cement mixer, forklift, dump truck, front loader, crane and backhoe, each approximately four inches long and a construction piece to lift and load. All are brightly colored with lots of moving parts that are fun for kids three and older to grasp and maneuver. Designed to play perfectly with Melissa & Doug activity rugs, the construction vehicles store conveniently or can be displayed in the compartmentalized wooden tray.
