Because us the real Kapla blocks are much too expensive for 3 children, we looked for alternatives and found here. Our children can build for hours with these stones and I am always amazed at what they build everything from it. From the boat to the big dollhouse everything was at it. The stones invite both the small children from 2 years and the really big in adulthood for a build. Of course, a bucket of 200 stones is not enough at all. We currently have 800 stone and more to buy. A very great toy that should be in every child's room.
