I personally think the product is not good for children. The pieces are very small and hard to put together. I sent a lot of time trying to get it put together myself. It would be fine as a duplo lego set. My granddaugher couldn't get the pieces to go together.
It was kind of what I was looking for. The only downside to this box is that the small pieces get stuck inside the inner rings that make the shape of the stackable. I don’t know if it is a fallacy on the design. I had to put contact paper so that the tiny pieces don’t fall inside
