I bought this toy for my toddler son. But so disappointed because all wooden blocks were stacked together by paint. I had to separate them by kitchen knife and it was so hard and dangerous. The paint is very roughly coated. One of the peg was very loose and had to be glued. The design is good to have so many shapes and colours in one but the uneven square block seems too difficult for toddlers to do. My son had no clue on how to pile them, get frustrated and through them on the floor. It is ok for older children but older children may not be interested in this type of toy.
