Pack Arco-Íris

The three spinners are the surprise hit here, my son keeps clipping them onto everything to watch them whirl. Forty-two pieces sounds like a lot until your kid builds a giant rainbow creature and suddenly wants more.

The click when the pieces snap together is weirdly satisfying, and the three spinners actually spin smoothly instead of wobbling. Worth every penny for

The spinners are the surprise hit here, my 6-year-old keeps building little spinning tops while my 9-year-old goes for the bigger structures. Only gripe is that 42 pieces disappear fast between two kids, so we'll probably need a second pack.
