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 are great. I feel dumb but I did not realize that they had stuff inside of them that mixed with the water and created a freezing gel. I was surprised how long they stayed frozen thinking they were just water inside but I just went to change the water and realized the water had become a gel. These things stay frozen all day in my insulated lunch bag. And they’re so thin that they don’t take up a lot of space in your cooler. I use all 4 & make a square around the edges of the cooler then put the food/drinks in the middle of the square. Drinks are still cold by the evening when I get home. These work amazing. And for the price, you can’t beat it. They work wonderfully even though I didn’t understand or follow instructions when I filled them up and filled them all the way to the tippy top. I highly recommend these! I’ve had way more expensive ones that didn’t work nearly as good

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.

I like the fact that its water inside the container. Any leaks are no issue. Works fine to keep my water and snacks cool during my golf rounds

Love these for the cooler for my son’s long baseball days. They leave enough room for a full bag of drinks and food and stay frozen all day.

Great product at a great value. Easy to fill and use!

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.

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.

Durable fill with water and freezer easy to clean light weight

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 .
