Then flip the tiles to build a school that they will have fun with for hours. All pieces feature SuperColor technology on both sides, for double the learning.

This schoolhouse is compatible with all Magna-Tiles Structures and original Magna-Tiles Sets. This set contains 1 six-inch square tile, 26 three-inch square tiles, 8 equilateral triangle tiles, and 2 door tiles. For ages: 3+ years.
