My daughter purchased these with her allowance and one of them was moldy inside. Disappointed.Bought as a gift for my 9 year old. She love the different kind of stress balls and how stretchy they were. Two of them were unusable straight out of the package. One was improperly sealed and oozing when squeezed. The other had thin patches on the surface that had small holes. I would have been a great gift if it had not been for the bad quality. I'm very disappointed in this purchase.Mold or mildew inside the snowman stress ballsThese do not hold up. One busted within a day. A stress ball that cannot be stressed!I purchased this item for my granddaughter because I thought she would like it and she did. The problem was that it had this real strong smell to it. Some say it smells like gasoline, others say it has this funky smell to it. Whatever it is, I threw it out!If I could give this product 0 stars I would. One ball came broken on arrival, and with mold all throughout the inside of it. The other balls hardly lasted 20 minutes of light use before breaking.At first glance these seem awesome. But after only a couple of weeks they are falling apart and everything is coming out of them. If you are looking for something to fidget with these are not it.Literally just air. Complete garbage.
