loved these as a kid and my daughters love them now. They love that it is easy to assemble, and they don't have to ask me for help. They have tons of different color beads in various sizes. They really do stick once you have put them together and aren't too hard to get apart. The size is great as it isn't too small for our youngest to want to stick in her mouth and swallow. They get to use their imagination to build so many different things with what is provided in the set....
