I got a 3 pack of these and two were immediately snagged by coworkers, so I ordered a new 6 pack. I love these balls! Its much more satisfying than the normal stress balls that bounce right back into shape, these are moldable and pliable and very durable. We've been abusing them pretty hard (including popping with pins, see tips below!) with no breaks, tears or leaks yet!

TIPS!!
1. There is an off-gas and a residue on the balls initially. At first it makes your hands feel weird, but this goes away rather quickly. The balls seem a little sticky at first but again, goes away quickly. First hour, if you dropped it, dirt stuck to it. But once the residue is off nothing will stick anymore. DON'T WASH IT OFF, THAT'LL MAKE IT STICKY!
1. AIR BUBBLES- some may have an air bubble in them, two of my original 3 pack had large air bubbles. I took a chance and a small safety pin and got the air out. It worked! There's now zero air, and zero leaks. The filling is thick enough not to go through a pinhole, and the tiny hole pretty much closed instantly because of the outside material. You can't see or feel where the whole was, and it completely solved the air bubble problem! When you stick the pin in, you're going to have to use the pin to stretch the opening so the air can escape. It really does seal itself right back up. As you play with it, the filling may compress creating an air bubble, but it can be fixed the same way, with a small pin.
3. DONT get it wet! It'll react funny with the residue on the outside making it sticky. You could sprinkle it in corn starch or baby powder if you got it wet, but it's really better to just keep playing with it. The residue will come off and so will the dirt, until it's not sticky whatsoever anymore (not ALL the balls had a residue on them!)

The 6 pack came in today and 3 already got snatched by coworkers who missed their chance on the first haul lol... These balls have quickly become our office favorite!

When you first got the balls, they're amazing. Dare I say, amaze balls? Sorry, anyway, the squish is soft, it fills your hand nicely, it's really good if you're trying to gain strength in that hand after a stroke, or surgery, or something similar. After a few days, the filling starts to get a little harder, almost like it's drying out. It starts developing large air pockets inside of the ball, making it much less satisfying to play with. For the first week or two, they do pretty good, but after that, they start to deteriorate a little bit. I have purchased two of the three packs on two separate occasions, and both times, at least one of them have come with a hole already in them. I wouldn't say they are a waste of money, but the quality isn't quite what I expected for the price asked. Still though, it definitely helps with anxiety, for sensory stimulation, for dexterity rehabilitation, for something to squeeze during a blood donation, or just generally having a fidget toy in your pocket. They do get dirty very quickly, which I guess is to be expected with a latex type of material.

Absolutely love these, but if you're aggressive and use a lot, they will pop

So fun, you don't even realize how long you end up fidgeting with it and the colors are super bright!

Bought these for stocking stuffers and they were a hit! Fun to squeeze!
