CHILLERZ Large Reusable Ice Pack (4 Pack) for Lunch Box – Long-Lasting Gel - Super Slim and Lightweight Cool Cooler Packs - Makes Your Food Stay Fresh, Cold and Tasty

Perfect size for a personal small coolers. So thin that you may use all 4 at once, lining the cooler walls. Used together with pre-chilled beverages, usually last at least 8-10 hours in my small soft side Yeti. Also great to use with ice. It makes the ice last much longer.

I’m very happy with these and will oder more. I’ve had them for over a month now and they work very well and the slim design is one if the reasons I purchased them. They keep everything in my cooler ice cold and sometimes frozen with ice, I only have to refreeze them once a week.

doesnt last as long because of the size/shape but it fits my lunch box perfect and it works as advertised

These work well and I like how thin they are - I often put them all around (on 4 sides) an item I am trying to keep cold in a thermal bag on the way home from the grocery store. So much better than one ice pack that keeps only a small part of an item cold while the rest of it is not kept as cold. I've used these many, many times and they have held up well so far.

The size is really nice. We have to double these up to keep food cold until lunchtime. Make sure you eat your whole lunch though- you'll definitely end up with room temp leftovers by the end of the work day.

These are great! Keep my lunch and drinks nice and cold through lunchtime and beyond. They are also nice and slim so they don't take up a lot of space in my lunch bag. Love them! Planning on ordering more!

These work great and stay cold most of the day. I do wish they were a little thicker but I just use all 4 and my lunch is cold all day.

Works great with the cargart cooler/lunch box-book bag.
