"Love that the fit in the pocket. Would need more than one if you need to keep lunchbox cold cold in hot months"
"This ice pack obviously fits in the rover lunchbags nicely, but it isn’t a great ice pack. One of ours got punctured and leaked, which makes it even less cold. In the summer, I use real ice packs if we will be outside, but this is fine for a couple of hours at school for what we pack."
"It seems like these should last a long time, but it's an item that I keep buying because it seems like over time the filling disappears - it is possible that the cells in the cold pack burst and the cold pack goes flat. I like that you can wrap them around smaller containers to provide chill on all sides."
"These cold kits fit perfectly and get the job done. They feel like they will last for a long time. I think they are worth it for the convenience and longevity factors!"
"Perfect addition to your lunch kit!"
"I'm using 2 of the packs together to make sure the food stays cold enough. The ice packs fit well in the box but are very thin."
"LOVED HOW SMALL AND CONVENIENT IT IS"
"Perfect for our need. Lunch box stays cool. I bought a second one in case the first one breaks or if we need to use 2 in the summer."
"Fits perfectly with the Planetbox lunchbox and easy to remove and clean."
"The material is nice, and it’s a nice touch to cover the cold pack with the material. I like the shape too, and it fits well in the planet box adventurer lunch bag. It’s lightweight. It’s mostly useless though as it doesn’t stay cold and just doesn’t have enough gel or filling to freeze! I don’t reach for this ice pack at all even though it should be the obvious choice to pack with my daughter’s rover."
