Learn & Grow magnetic tiles have been designed to encourage imagination and inspire open-ended play. Magnetic tiles provide children with open-ended experiences where the only limitation is their imagination. Each tile has strong magnets to allow for tall buildings and structures that do not continually fall down and frustrate little builders. Sets can each be added to expand play opportunities and are compatible with all major brands. Manufacturing: Made from strong food grade ABS plastic, riveted and plastic welded with an internal logo to create a flat and more scratch resistant tile.
