Freezes solid and fit lunch bag nicely. Positive experience to report.

Love these slim ice packs. This is a repurchase for us.

Works great with the lunch box and bag! Lunch gets packed early and stays cold all through lunchtime and after school.

These are the perfect size and have lasted all day.

These are as pictured, skinny icepacks that fit nicely in a lunch box. When they're frozen they bulge a little bit, but that makes sense since water expands when frozen. Since they're so slender they don't have a ton of thermal mass, but they kept my salad cool enough for the shredded cheese toppings to not be stuck together, so I'm happy. I like that there's four because I can forget to put one in the freezer and there's still three left I can draw from in the morning before I head out.

I bought these to put under a towel for my pets to lie on when it's hot out since we don't have AC. They're nice and thin, smooth, and flat and work really well for that! I arrange the 4 together in a rectangle and cover it with a towel. They are probably also great for lunches ;)

I was hesitant to buy these because did I really need a 4 pack, did I really need this brand? Yes. These are perfect in our son’s lunchbox. We have a Cat & Jack soft lunch box we use with the Bentgo Kids. I put two of these side by side and they fit like they were made for the lunchbox, perfect fit. They’re thin enough that I could even put the other two on top if needed without any issue. My son has lunch at 11am, so I really only need these to stay cold for about 3-3.5 hours, but when he comes home at 3:30pm, they’re melted, but still cold. I wish I didn’t purchase a different brand a week before I found out about these bc I don’t even use the other ones now.

Fit perfectly lunch box, 2 of them, and way to clean

Great chillers. They work well inside a cloth lunchbox surrounding the Bentgo box itself; not sure if that’s how they’re supposed to be used, but that’s what we’re doing and it works great. Gender neutral, so will work for my younger child as well.

These ice packs have been perfect for adding to my daughters lunch box. They fit perfect in the front pocket of her lunch box due to their sleek shape and hold freeze all day long.
