I don't have a larger Doll Leaves, but I do have a Dan and a Fay. Dan is 26cm and Fay is 20. Both of them stood rock solid right out of the box! I think that they have excellent posing, solid resin and nice quality. The only problem that I have with mine - which may not be true with the larger dolls - is that the heads do not move. It has to do with how deep the S hook trench is inside the heads and I'm experimenting with using some plastic washers to try and solve that problem.
Again, the head thing may just be an issue with the smaller dolls and not an issue at all with the bigger ones - I will say that it would not stop me from buying another one if I saw one I wanted
