A workman's job is never done. But thanks to the Melissa & Doug Stacking Construction Set it will be a little closer to being done after these machines get started. Just as is the case with all of the stacking vehicle sets, this construction set features three different type trucks that can be disassembled and rebuilt over and over again. They are all three colorful, clunky and solidly built for years of heavy play on any construction site. These include a dump truck, cemet mixer, and a bulldozer. Your child will wonder how they ever got a project off the ground without them. Union membership not required.
