Twelve wheels and colorful flexible joints can traverse tough terrain. When developing the product we thought of the Mars Rover! Great for toddlers to push along or add a string on the front hitch and pull it through all kinds of inside terrain - over the pile of books and under the bed? Crafted from hardwood maple, the Rover measures 13 1/2" long, 4 1/4" wide and has 1 3/4" diameter wheels. Comes shrink wrapped.
