Magna-Tiles were invented in 1992 to teach children about shapes through play! Each tile has magnets along it's edges. The secret is the unique ability to attract even when the tiles are flipped. They always connect! Sized just right and easy to use, Magna-Tiles develop fine motor skills as they start by stacking, making flat patterns, and 3-D shapes, and with time, create complex Magna-Tiles creations.
