WISYME 4Pack Glow in The Dark Sticky Balls That Stick to The Ceiling,Stress Balls for Kids and Adults, Dream Balls That Come Back to You, Lumiballs

They are great for fidgeting around. However, if you are getting these for children, be aware they could open up and spill the contents easily. I use them as an adult and the durability is not great. For the money, they get the fidgeting done.

I really wanted to like these stress balls, but I’m super disappointed. One of them arrived already popped, which was frustrating, but I figured I’d give the rest a try. Big mistake! Within just four days, every single one either popped or started leaking—and I’m talking gentle use, not rough squeezing. They didn’t stand a chance!The concept is fun, and I loved the color-changing idea, but the quality just isn’t there. If you’re looking for something durable, these definitely aren’t it. Save your money and go for something more reliable!

Listen, I was not really under the impression that I found a holy grail item and got an amazing non-toxic, all natural, safe fidget toy for cheap. I had a feeling they were going to be rubber or silicone of some sort. But for an item that posts all over their products that they do not smell and are not sticky, I was hoping for at least one of these things to be true. Alas, they were both lies.These smell so bad! Like give you a headache kind of bad. And they are sticky to the touch. I will say that none of the sticky residue was left on my hands, but the smell stayed.The give and stretch is nice and they are very easy to just roll around and mold in one hand. Despite the smell and stickiness, I will be keeping one at my desk. Fingers crossed and least the durability claim holds true.

These held up very well against the destruction of our boys! I honestly can't believe none of them have broken yet and it's been a few weeks.

update: two days later, another ball is leaking. this one was being used by a 90lb daughter.original: on the positive side, the feel is outstanding. slow deforming, thick, and gooey. unfortunately it took only about 10 mins of normal squeezing (like a stress ball, not stretching, not twisting, not puncturing) before the "navel" (sort of a plug through which presumably they filled the ball) split open at the seams. all of these balls seem to have poor durability reviews, but i was hoping that maybe some people are just unfairly rough on their balls to stress test them. i was not. mine failed quickly from normal squeezing.

I bought these for my daughter when she broke her arm after wearing a cast for a month her strength was weak so I wanted to get her strength back in her hand, and each one was different. From easy to squeeze to hard. Do not buy them for infants because I have a nine month old, and she grabbed one from her sister and the first thing she did was take a bite out of it, and it broke and leaked out all of glitter and the gooey stuff . But my 5 year old daughter loved them and they are all very colorful and fun to play with. She doesn’t need them for strengthening anymore so she just plays games with them now

I bought these for my Mom. She's on hospice and bedridden. We don't want her muscles wasting, so I guide her in bed exercises. Bought these for her to strengthen her hands. They are cool looking, but she won't use them because they are sticky. It doesn't get on her hands, but she hates the feel. Great for kids!

I got these for my daughter, and in less than a month, they had ripped open and the stuff inside just oozed out.
