This item is superb as it is not just another shape sorter it is also a toy train. Its colorful and unique. It is a Montessori style and ideal for home and school. There is so much you can do with this one. The front of the train consists of four rings, a hammer-shaped crossbar and a screw. Take the screw down, take off the four rings, you can remove the front of the car. You can teach the shape and color while playing. Great for early shape sorting and identification. Its also good for colors and patterning.
