Dry Ice Packs for Shipping - Long Lasting ice Packs - 24+ Hour Freeze Power - BPA Free - 12 Pack Bulk 3 lb – Hielo Seco - Reusable Gel Bricks for Food

These Work Exceptionally Well, They Freeze in a Few Hours. I Freeze A few in the Night 4 the Next Day. I’m One Happy Camper Now That I Found Luna XL Ice Packs. I Will Be Ordering More 4 My Family Members too When We Go Camping. They Are Going To Really Enjoy Them As I Certainly Do🙂

These work great! I use them for overseas flights. Worth the price and reusable!

These are a great find❗️Economical, sturdy, and the sheets can be pulled to separate the squares with ease.

They did not work for what we intended them for, but most likely with a Styrofoam box they would be perfect for shipping. I enjoy that these are just as easy as "just add water and freeze" ice pack. I never have extra room in my freezer for anything but these were perfectly small and compact. They are great for lunches, afternoons out, and only for the day uses out and about. They are perfect to take with in your lunch box because the the food is gone you can throw these away instead of trying to remember to take it back inside and refreeze. They ended up having great uses even if it wasnt for the intended purchase. There were a great amount in the package for the price. The quality is great for short term use, they didnt leak until well after 12 hours when they were completely unfrozen.

These freezer packs work great for general usage, and as long as you follow the basic instructions, you shouldn't have an issue (barring manufacturing defects). The sheet includes 12 individual "cells" that are perforated for easy separation, allowing you to customize the layout/coverage as needed, and do actually last a surprising period of time. Note that when you first hydrate these, if you place them under running water, watch them closely, as you can hydrate them to the point the cover is stretched tightly, making these more round than flat, and harder to flat pack in your container. I've only used a couple of them a few times, but so far have not had leakage issues, but they are colder than some of the other gel packs I've used (I froze these as per instructions for 24 hrs prior to using them) and did have more condensation on the non-mesh side than with other gel packs. Overall, these have been a great solution for small portable applications (I have a leather dog treat pouch I made for "high value" reward treats, and some snacks for me, I wanted to keep cold/cool), and even on longer walks in 80F+ degree temperatures under direct sunlight for 1+hrs, the contents stayed cold to the touch and fresh, something I've been having trouble achieving with non-gel ice packs.

It’s a nice product if you use just for a day and have the ability to put back in the freezer to be refrozen, but as a flight attendant, it did not work for me and now only after two months of use the packages are ripping and the contents of the inside are coming out. I’m going to have to dispose the packages so I don’t think it’s worth the price for only a couple months of use.

Great product for women with menopause needing cooling relief! Wow! just what I needed for a 20 hour flight from USA to AUSTRALIA! I packed in an igloo slim lunch box with an ice floor 2 frozen bottles of water and 2 Xl packs and 2 XS PACKS LUNA ICE. the ice water bottles were still frozen when I arrived. Packed the lunch box in my carryon and the water was still 1/2 frozen after 2 days. I placed the XL Packs in the hotel fridge and the product remained partly frozen.

The dry ice packs worked okay for shipping and kept my items cool for a decent amount of time. However, they didn’t stay cold as long as I expected, especially during longer transit times. The quality seems average, and while they get the job done, there is definitely room for improvement. Overall, not bad, but not amazing either.

also stay cool for extended periods of time.

Easy to use and reuse, it’s so cool that it comes in flat sheets and you just allow the water to run into them and fill to desired size. Freeze and they are ready. We left ours out at 22oC temperature to see what would happen and they lasted 7 hours, without being in any cooler and never lost a drop of moisture. Definitely will buy more in the future! Great product.

I’ve ordered product similar to this and I was looking forward to them staying in large pieces however once soaked in water they all fell apart into individual pieces not very useful except for lunches

molded after a year of use. Maybe i let it sit defrosted for too long but it wasn't fun to discover. I would keep majority just in storage and use 4 at a time. I like how its compact to store and you can shape it into whatever you want in the freezer.
