The Magnetic Skeleton Maze is based on the Award Winning Magnet Express and is two-fold educational: promoting eye-hand coordination, visual tracking and fine motor skills and introducing children to the skeleton of the human body! While children use the magnetic wand to guide the balls through the path, they will become familiar with bones throughout the body.   Great for doctor?s offices, schools, the home and travel. No loose pieces!  Ages 3+  12"x 20"x 1"
