This is a set of 3 non-motorized spinning discs. While self-assembly is required, they’re really easy to put together and the counter-sunk boards allow the discs to fit snugly inside. It's a 3-tier kit that allows you to make a Rubik's cube where each layer spins independently. It comes with a full-length tutorial.
 
This kit is from our Retro/Pop Culture Month event. Now Dawn is sharing it with everyone!
