KonaIce Packs for Lunch Boxes - No Ice Bags Required - Reusable Long Lasting Cooler Ice Packs (-5C) Small Thin Freezer Packs - Freezes in 25 Minutes (Set of 4)

Work very well without taking up much room at all. Last all day in my standard Stanley cooler. Seems to keep drinks cooler with it's lower phase change. Allows me to take more in the cooler because of small footprint. Recommended and will purchase again in the future if needed. Happy with purchase and quality. Easily refreeze for use in a short period time.

My wife really wanted to have some good slim ice packs for lunches and we have been very pleased with these.

These are thin, so they fit into lunch box easily without taking up much room. They work really well.

They work as they should. I leave them in the freezer and pull out when loading up the cooler. These are pretty thing (exactly what i wanted to line the walls/top of cooler with the cold packs).They dont last super long but it kept my drink cooler cool for ~12 hours in the Florida sun with a cheap plastic 15 liter cooler. The drinks were cool at the end of the day, not ice cold. This i believe would work best in a lunch box or as supplemental cooling along with a larger ones to add cooling from the walls/in the middle.

We give these thumbs up. They freeze quickly and last for school lunch.

I bought these to use instead of the soft ones that my Titan lunchbag came with. I like that they are slim, they fit perfectly, and they don't need a perfectly flat surface in my freezer like the soft onces.However, they thaw so fast.... within a few hours, they were 15 degrees warmer than the Titan ones.I will return them. Love the shape, but not the function.

I bought these to go with my Kanga Coolers. Great purchase. They keep the contents of your cooler chilled all day.

If you have a small lunch bag, you know how it goes when you add a chunky ice pack to them. You're barely able to add all of your items into the box without shoving stuff in and creating a hard-to-zip bag. These are PERFECT for those situations, they barely take up space, allowing you to have room for snacks or bigger meals. I work 12-hour shifts, and I don't know what I'd do without these. I can fit my breakfast, lunch, AND snacks all in the same bag without worrying I'm about to break my zipper!

These are a perfect size not taking up too much space yet ensuring your food/drinks stay cold

It’s advertised as 1/4” x 6.25” x 4.15”, what i got was 1/2” thick instead. Not the same thing, I bought it for its thinness, not to have it twice as thick as advertised.
