desertcart.com: Dynarex Disposable Ice Packs for Injuries - Instant Cold Packs for First Aid, Swelling, Sprains & Abrasions - Single Use Cold Pack & Cold Compress Packs for Joint & Muscle Pain - 24-Pack, 4X5-Inch : Health & Household

Review: Great product for when you need a cold pack. - Why did you pick this product vs others?: Used these for a while and they work great and last a long time. Easy to use and carry with you for when they are needed.
Review: Best, least expensive, instant cold pack BY FAR! - As a former varsity volleyball player and currently an avid outdoors person, I have been using cold packs when necessary for years. No instant cold pack can compare to ice cubes in an ice bag in terms of the amount of coldness or length of time the coldness lasts; however, there are times when you can't immediately get ice cubes and/or carry your ice bag (or your ice bag leaks during a 3-hr flight -- that was fun, especially for the next traveler assigned to my seat). That's when it's more than handy to have an instant cold pack -- it can literally reduce the pain of an injury, animal bite or insect sting, just to mention a few uses. I have tried just about every instant cold pack available -- big box stores, pharmacies, online, you name it -- and with one exception up until now, they are pretty much worthless. There are ones impossible to activate, ones which harden like a rock if you store them in your closet for less than a month, ones which are barely cool when activated, ones which are the size of postage stamps, ones that don't even stay reasonably cold for 10 minutes. Up until I discovered the Dynarex Instant Cold Pack, the only one I could depend on was the Ace Instant Cold Pack at $7.67 for a twin-pack on desertcart (much more at my neighborhood pharmacy). That comes to $3.83 apiece. I bought the Dynarex 5"x 9" instant cold packs in a box of 24 (yes, twenty-four) for less than $20 delivered. That comes to $0.83 each. I checked each pack in the box and all are just fine. I have used them and they easily activate, they are generously sized (larger than the Ace) and the cold lasted at least 1/2 hour. I can highly recommend them. No, I wasn't given any external incentive to give this great review; my internal incentives were 1) to help other people find a portable, easy-to-use, handy and really decent quality instant cold pack and 2) to give a shout-out to a great instant cold pack manufacturer who deserves it.

## Questions & Answers

**Q: If used inside an insulated foam container, how long will these continue to operate near peak value?**
A: For long lasting ice, save your 16oz water bottles. Fill them almost full with water and leave the cap just a little loose and put them in the freezer. When frozen securely tighten caps. Use the frozen bottles in place of ice cubes to keep an ice chest cool and they will last DAYS, and you can finish them off as ice water. I've done this for years and it' amazing how long they remain frozen.

**Q: does the product contain ammonia nitrate?**
A: No they do not. the contain calcium ammonia nitrate. No good for tannerite. It must be a new policy

**Q: is this toxic waste or hazardous materials?**
A: Here is the Material Safety Data Sheet for this product, provided by the manufacturer: http://dynarex.com/resources/MSDS/MSDS_Instant_Hot_And_Cold_Packs_(4511-12,_4515).pdfAccording to this: 'This material, if discarded as produced, may be a RCRA "characteristic" hazardous waste due to the characteristic(s) of ignitability (D001). If the material is spilled to soil or water, characteristic testing of the contaminated materials is recommended. To assure proper disposal, consult with state and local regulations and disposal authorities.'I called my local county Haz Waste office and the officer couldn't tell me whether Ammonium Nitrate was considered haz waste where I live, but requested I bring it in to Haz Waste for disposal. Although ammonium nitrate is a fertilizer, many agricultural chemicals are considered hazardous waste.

**Q: are they allowed on planes**
A: Get an old fashioned hot water bottle, put it empty in your carry on and when on the plane ask the attendant to fill with ice. Put a little water inside, put it inside a plastic bag and it will last for about 30 minutes. Repeat! No waste, no cost!

### ⭐⭐⭐⭐ 4" x 5" Dynarex cold packs - recommend
*by E***T on November 22, 2020*

I just tried these for the first time - usually I get the full-size ones, also by Dynarex. These are about 1/2 to 2/3 of that size. I found both sizes effective and relatively easy to use. Have never experienced a leak or failure. My observations on these small packs as compared to the full size ones: Pros:: Easier to store/takes up less space in car, gym bag, First Aid kit Lower price Gets very cold, same as the large ones Easier to activate (you have to squeeze the pack, and the big ones can be a challenge if you have arthritis) Cons: Treats a smaller area - good for small bumps/areas of pain but would be too small to wrap around a limb Doesn't stay cold as long So I would recommend either one. Next time I will probably get the bigger ones because I use them on my neck.
