My granddaughter likes to build little compartments and match these balls with the pastel magnetic blocks.
I purchased this set along with the 106 Piece Pastel Ball Run Set (which includes 8 balls), so all together we own 24 balls, and I believe that I made a right decision! My toddler enjoys watching the balls run, and we also use all the balls for other activities like color sorting, scooping, as well as putting them in and taking them out of a bag (this set did came with a small canvas bag for you to keep all the balls inside, which is a great plus to me).
Nice colorful balls for our ball run set. My toddler is so excited every time we put all the balloon the ball run.
