Magnatab is just like pen and paper - but it can be used again and again. Designed with the Montessori learning style in mind, it creates a sensory-based learning experience. As children use the magnetic stylus to draw pictures, letters or shapes, the beads are raised to the surface. In doing this, they feel the pull of the magnets, hear their clicking sound, and see what they are drawing. To erase, simply swipe across the surface with your finger or the side of the stylus. Terrific for travel, school, home and more. Measures 6 x 7-1/2 x 3/4". For ages 3 and up.
