This is a terrific, detailed construction site complete with a working crane, a sand hopper, diecast vehicles and working parts. Your young builder will enjoy filling the trucks with sand and stones and moving them through the construction site. The crane pivots and everything is very well produced and very detailed. This is a great product to follow through and visit an actual construction site. Also the puzzle by Frank Schaffer of the giant bulldozer will make a great combo for added play value.
