I do like that they snap together to put a layer on the bottom, some drinks, another layer and some on the sides. They stay cold for a few hours on the beach.

I use these in the bottom tier of my sons lunch containers. They keep the sandwiches, produce, and snacks cold. Even during a 12 hour shift.

Love how it keeps my food cold until my lunch and it doesn’t make a mess when it melts. The only thing I don’t like is that you can’t puzzle them together once they’re frozen because they don’t fit. You have to put them together before you put them in the freezer.

These stayed frozen and kept food cool on a travel day for 8 hours!

Just love them. It works for my teens lunchbox

The ice packs are slim and they fit in almost every cooler bag.

It's not as cool as I would like them to stay. By the 8 hour mark, the packs melted already. The packs are still cool but like refrigerator temperature.

That they are slender and can link together to form a larger ice pack or a box around food.

Hardly remain for 1 hour
