I bought this set for my son when it was on sale, mainly because I was drawn to the colors, and it had some unique shapes. However, I did not realize some of the really cool features of this set- some of the pieces go together magnetically and allow you to place them on cylinder blocks to make a functional car! My son figured this out, and it’s still his favorite feature. He likes to used the gray itself as a little house and put dollhouse furniture in it. Then he uses the blocks to build things around it that would be part of the yard or a house for the attached little dog. Taking one star off because the blocks are slick if that’s not your preference. Otherwise, a beautiful little set that scales with unit blocks rather than euro blocks.
