The stones are not very big, but well suited for small children's hands indeed. I especially like the delicate wood and rounded edges and corners. The 100-ton, he was opposed to the 50-ton it a bit better sorted with us, that is the ratio of the types of stones with each other was a bit more balanced. Nevertheless, there is a star trigger that two stone types are highly dominant (cubes and flat square, 30 pieces each), while there are not enough other great stones (eg. Bridges (4) and cylinder (3)). The ratio could thus definitely be much better!
