## Questions & Answers

**Q: Does it freeze as a hard solid? Or instead is it pliable when freshly frozen?**
A: Thank you for your question. Our Gel Blox freezes into a solid "brick" of gel. However, our Therma-Kool Hot Cold Gel Packs (used for first aid & therapy) are soft and flexible when frozen. - Nortech Labs Inc

**Q: Can you use them for international travel or are they TSA approved?**
A: I used these for medication for a trip overseas and had no issue. I did a double bag; meds and gel ice in smaller bag and smaller bag in larger bag with gel ice. It worked fairly well. I contacted a pharmacy at first airport and they had another ice pack ready for rest of my trip. Complicated but my meds arrived safely. Tip: take med bag out of carry on in separate bin at TSA. They will want to look at it.

**Q: Could it fit into a 4"x4.5"x1/2" tray?**
A: Thank you for your question. Since it turns into a solid brick of gel, it may be too large to fit into a tray of that size. However, we do carry a 3 oz Gel Blox Cold Shipping Pack that is 3.5" x 4".

**Q: For how many hours do these keep things cold?**
A: We took a cooler to St. John USVI and the entire trip from home to villa was a good 15 hours and when we arrived and unpacked the cooler they were still frozen.  They worked great!

What I needed

### ⭐⭐⭐⭐⭐ long-lasting and durable
*by R***8 on June 3, 2014*

Needed to keep insulin cold for two to three days of travel so I needed something long-lasting. These paks held up brilliantly. The paks were both still very cold on day three. I would definitely use these again.

### ⭐ NOT WHAT THEY SAY THEY ARE
*by A***R on July 29, 2018*

Unfortunately these are the only ones i can find but they last no time they do not keep items cold and have had so many complaints with this item with shipping. They melt almost instant anf ruin food or any other product so DONT WASTE YOUR MONEY LIKE I DIDM
