The Magnetic Skeleton Maze design is based on the Award Winning Magnet Express. With the attached magnetic wand, children guide the balls through the path, becoming familiar with bones throughout the body. The Magnetic Farm Maze is a great educational toy that promotes eye-hand coordination, visual tracking and fine motor skills as well as introducing children to the skeleton and circulatory system of the human body! Great for doctor’s offices, schools, the home and travel. No loose pieces!
