Kids step their way to physical fitness—and develop balance, coordination, gross motor skills and concentration—as they step from one stone to another! These lightweight yet durable stepping-stones are a cinch to set up and move around indoors and out, so children can create a variety of paths. The stones feature two different heights, and each is lined with a rubber bottom to prevent sliding. The 5 plastic stones come in 5 colors and stack for storage; largest stones measure 12"w x 12"d x 6"h.
