Magna-Tiles are the beginning of something beautiful. Magnets adhere in all directions. They click and pull apart for sensory satisfaction. Kids are starry-eyed over the crystal-clear transparency and the magnetic attraction. Beyond that even, the extra-versatile accessories within the 48 piece Magna-Tiles pave the way for imagination and bring the fun home! A wheeled chassis - roll into creation of bulldozers and race cars. A hinged door - open and close that barn, space hatch, and dollhouse door. Hole-punched triangles - peer into windows and knotholes of trees. Curved arch - race ahead with plans for a train engine and swimming pool. Young children learn about color, shapes, symmetry, size and scale. Problem solving becomes a whole new attraction. Fine motor skills grow right along with conceptions of all that can be imagined and built!
