OUTXE Ice Packs for Lunch Box - Reusable Ultra-Thin Freezer Packs - Long-Lasting Cool Packs for Coolers, Keep Food Fresh and Cold in Lunch Boxes and breastmilk Bags

These stay cold for a LONG time and keep your food cold as well. The small, narrow depth of these are great as they don't take up much space in cooler.

I buy new ice packs for the kids lunchbox every year before school. I decided to buy these as they were a fraction of the price as the normal ones that I usually get. I’m glad that I did. I really like how thin they are. I can actually fit other stuff in their lunchbox as well. I have had no issues with leaking or any other issues with them. We will re-purchase.

I just got these, and they have been in the freezee for less than a day, so I don't know how well they cool a cooler or how long they last. However, they are a fabulous size, just perfect for my lunch box, and pretty thin, so they don't take up much space. They also feel sturdy, like they will last a fair amount of time. My biggest problem is that the indtructions say to 'fill with water to fill line'. The only probkem with that is that the material is a thick, opaque plastic which makes it almost impossible to know when the water has reached the fill line. Also I was not fully confidant in the tightness of the caps when screwed on. I may go back in and glue them on at some point.

Keeps drinks cold in cooler and all you have to do is fill it with water and place in freezer it is thick and has grooves to plus soda cans and keeps soda cans in place in lunchbox

Great ice pack! It's light weight and does a great job of cooling your lunch bag for hours.

I love how thin and wide these ice packs are. I pack my 9 year olds lunch every day and they do not add a lot of bulk or weight to the lunch box. They are also easy to clean. I also have beach chairs with built in coolers and these work perfect in there as well.

After 2 months of use I've found that the ice packs develop a bump on them after freezing. The bump makes them around 20% thicker so not great if you're trying to maximize the "ultra thin" aspect of these packs. They were good for the first 2 months, lasting from 7am to 2pm in a cheap insulated lunch box easily. Never needed them to go longer so I didn't pay attention to how much longer they stay cold. They have a gelling substance inside that looks like salt, don't remove it. Wouldn't buy again but I guess they're fine for $8, certainly not meant to be high quality so you get what you pay for.

Didn’t like to have to fill my self and can’t see water inside to fill to fill line but they work

So disappointed. These come with a cap and you fill them up with water. If I wanted a water bottle I would have gone to Kmart .
