These balls are great! My little one loves jumping in them, and with that, stepping on them.
Even with her, 27lb 2yr old, stepping all over them, they keep their shape. I just wish these were a little cheaper since this bag doesn't go very far, you need quite a few to make any sort of puddle in a ball pit, but I did find these in store for half of the price, so can't beat that!
I would definitely buy these again.
I have an inflatable pool in our basement and I bought these to help add to our collection of balls we already have. They matched the colors we have and are good quality. I have bought bags here and there and I noticed that these ones do not crush like some others I have purchased.
