Not a shape sorter at all
This toy is not at all what it appears. Although it is true that it is sturdy, the top comes off so easily that there is no way for it to be a learning tool. It is rather a bucket with blocks and you could buy that cheaper or make your own with things you already have. Our 10 month old took the top off and almost started to chew on it in the first 5 minutes of having it so we returned it and are now in the hunt for a better one. Don't buy this toy if you are looking for a shape sorter!
