Clever Instant Cold Pack | Disposable Ice Packs - Cold Therapy - for Injuries, Swelling, Inflammation, Muscle Strains, Sprains, Perfect for First aid Kit, Outdoor Activities, Athletes. 5x7 in. 24 Pack

I can’t relate to those saying it was hard to activate. I’m a relatively small girl, 7mo pregnant, and popped it on my first try. It instantly got cold and lasted about 10 minutes. After 10min it started losing the coldness, sort of as expected.

I purchased these because the description says they were the older type (A N) which is false. They dont get ad cold or last as long.

Comes in 4 separate boxes which is ideal for traveling and packing for tournaments and practices etc. My son used 3 of them the day I got the package , fits in sock nicely to hold on the ankle. Not too big and not too small, good size. I would purchase this again if needed- always good to have these in the car or handy just in case, it's not always your son that needs it so be a Boy/Girl Scout and prepare and plan ahead for every contingency.

These are pretty basic instant cold packs. Just like many other ones, you pop the inner pouch and the chemicals inside mix together becoming cold. So there's not much to it. These are much less expensive than other ones, so the value is definitely very good. The only thing is that I wish they got colder. These get cold, just not ice cold. A bag of actual ice would definitely be colder. However, I think this is the same with all of these type cold packs. I've tried several different brands of the instant cold packs and they are all about the same level of coldness. So it's not a defect with this brand, just something to be aware of with this type.

I bought the 24 pack and none were popped or broken or spewing out, unlike some of the negative reviews. They were all in great shape. I tried one out right away. It takes a good squeeze, as most due, to pop the inner contents to start the cold process, but it wasn't that difficult. Definitely don't cut into it, pound it with a hammer, or anything like that to get it to pop as that won't make it work right. I shook up the contents and it immediately got cold and lasted well over 30 minutes at the coldest and then diminished slowly after that, which is what these are meant to do--provide temporarily cold for injuries. So, if you're expecting hours of relief from one package, that's unrealistic. If the contents are shaken thoroughly, that will reduce your results, too. But following the directions and knowing what it's all for seems to produce the results one should expect. So, I'm very pleased with these.
