## Questions & Answers

**Q: will these be good for shipping chocolates?**
A: We brought them in a cooler with meats and frozen pizza. Over 2 days of driving, the dry packs were still  ice cold. You could use them for shipping chocolates, if the chocolates arrive in one or two days.

**Q: Once they begin to defrost do they leave a pool of water behind?**
A: Any frozen item left in the room air will cause condensation of the water in the air causing the water to cling to the cold item.  The item appears to sweat water. That is just the moisture in the air clinging to the cold item.

**Q: How do you store them in between uses. do you have to drain and sry them so they dont get moldy? do you re-soak before the next use?**
A: No. Put it back in the freezer for future use or leave it in a box.

**Q: How long will they stay cold if used for shipping purposes to keep soaps and butters from melting during summer months?**
A: We used 3 ice packs in a shipment of whipped skin cream which took 3 days to go from a 90 degree location in FL to an 85 degree location in AZ.  Upon arrival we were told the packs were no longer frozen but they and the skin cream were still cold.  That was satisfactory for us.

### ⭐⭐⭐⭐⭐ These stay frozen all day!
*by N***3 on 28 February 2018*

I'm a Personal Grocery Shopper and to ensure any and all cold and frozen items are delivered to my customers still cold and frozen, I use these with my insulated bags. These work so so incredibly well! I've had mine since September, I bought a 50 pack of them and split them with a couple of fellow shoppers I know. They stay frozen all day and I've even left them in my bags in the back of my car overnight and found half of them still frozen but all of them were still cold enough for me use again that day for orders! I have noticed they can get a little bit slimy when they're thawing out so I put them in Ziploc freezer bags, I put 2 in each freezer bag plastic side to plastic side bcuz if I freeze them with the fabric sides together they get stuck together like that and I've had them rip. Keeping them in Ziploc bags also stops stuff from getting on them and keeps anything from absorbing into the fabric side of them. I've used them for my own grocery shopping as well and they've kept my ice cream frozen solid during the hour and a half it took me to get home! I also like how flexible they are, I can rearrange them as needed to fill my insulated bags up all the way with cold and frozen food.
