Healthy Packers Cool Pack, Slim Ice Pack for Lunch Box - Quick Freeze and Long-Lasting - Freezer Cold Packs for Cooler Bag and Lunch Boxes - Original Long-Lasting Formula (10 pack)

Having two school age kids that like to bring their own lunches, these are very cool. I like how they are flat, and not a brick bouncing around the lunch box. They can rest under the contents with ease and keep their stuff cold. My package came with a stack of them, so there are plenty for the household. There is nothing complicated about these, and they are fun colors to keep it interesting. Each one measures about 5” by 5” and they stack well with each other. I like them and would recommend them to others.

This ice pack comes with a set of 5 in different colors. I used them in my lunch bag and I only have to use 2 at a time depending how big my lunch is and they are long lasting as well one alone lasts about 5 hours before it defrosts. The more you use the longer they'll last. Convenient and easy to use.

These ice packs are perfect for lunchboxes. I pack a lunchbox for my son when we are out and about for the day and the ice pack is thin enough that it doesn't take up much room but at the same time keeps cold for hours. My son enjoys being able to choose a different color each time. I have also put one is a bottle storage bag (made for baby bottles but we now use it for water bottles) for when we go to the park and it has kept our drinks cold even while the sun is beaming down on the bag.

This pack come with five freezer ice packs—each one a different bright, fun color. They are a durable plastic square that had a round hole in the middle. They aren't hardy enough to keep a lot of food cold, but they are perfect for throwing into my husband or kid's lunch box—they aren't bulky, so it leaves a lot of room for the actual food in the lunchbox. The colors are fun—my kids enjoy choosing which color they get in their lunchbox each day.

I bought these to travel with, i freeze them and can take lunch with me to the airport/on the plane. so far so good, took em to Hawaii, and then had them to take to the beach too!

Love the size and qty of these! Perfect for kids lunch boxes

Both the color and the size are very good. Since there are five ice blocks in one set, so there are a lot of match selections. Moreover, the ice blocks are very thin and only take very small space in the food bag. I used to worry about my lunch getting bad due to high temperature, and the issue is solved now. They are also functional. I tested them by putting them in an insulated lunch bag with a grapefruit. 5 hours later they are still cold and it was 70-75 degrees the whole time. I love their size. They for perfectly in the lunch boxes we have. For extra coldness you can put one on the bottom, one in each long side and one in the top. They are very slim and don't take up much room. Kids will be happy with their lunches kept cool once school starts up again ☺️
