Query: Very Cool

We gave these to our 3 year old on his birthday because he is obsessed with robots. These are the coolest toys! Very fun to stack, they give you pictures of some patterns you can try. My 6 and 7 year old girls were loving them and we were too. Definitely think 2 sets would be twice as good.It teaches kids balance because most of the stacks have to be balanced on both sides in order to stand up. And of course my 3 year old loves to knock them over!
