This is such a cool idea. The execution is a bit lacking though. The pieces need to be assembled, which would be fine, but they don't fit together snugly, in fact they are very loose. That means they won't stand on their own without some fairly involved glue work. It takes quite a bit of effort for them to be usable so don't expect to use them right out of the box. If you are ok doing a fair amount of work then they are great.
