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 ice packs work exactly as expected and are a great option for shipping items that need to stay cold. They’re easy to activate, freeze well, and stay cold for a surprisingly long time when paired with an insulated box. I also like that they arrive flat, so they don’t take up much storage space until you’re ready to use them. Great value if you ship food, medications, or other temperature-sensitive products regularly.

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.

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.

Comes very compact, each pack swells up nicely in water, freezes to the same size, lasted for at least two to three days before totally melting.

I love using these for my frozen items for my grocery runs, it helps me not have to cut my errands super short because I have frozen items to keep cold! They’re also great for lunch boxes.

They work well, however don’t expect to keep them longer than a few seasons. They hold onto scent pretty bad. They’re cheap and efficient though so what can you really ask for?

Easy to prepare but did not last. Shipped a package to Florida and they were melted in less than 48 hours. Insulated and iced package wasn’t cold or warm - just room temp. One item didn’t make it.

Truly does last for over 24 hours. I bought these for an 8 hour car ride. They were still frozen when I got to my location. I tested them again on a 48 hour work day and by the end of the second day they were still cold but not as frozen. I decided to just leave them in the cooler to see how long it last. By third day it was room temp. I put them in a zip lock but there was zero water as it cooled off. Easy to freeze, just run cold water over them for three minutes and put them in freezer overnight. This product is definitely worth the purchase.

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.
