OICEPACK Ice Packs (set of 6) Cool Pack for Lunch Box Freezer Packs for Lunch Bags Coolers Ice Pack Slim Reusable Long Lasting lunch box ice packs interlocking Ice Packs as Ice Cube cooler Blue

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.

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

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.

Just love them. It works for my teens lunchbox

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.

I absolutely love the concept of these. When I got them I immediately built the cube and thought they were great. However, after freezing them, I love them less. Because of expansion, they don't fit together very well. I've ended up just using them as small, flat ice packs. As small, flat ice packs, they work very well, but they are very small and definitely don't encase your items like I had hoped. They don't take up much space in the freezer, especially if you stack them while they're unfrozen, but again due to expansion, they wont stack nicely if you stack them after freezing.

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

Awesome little ice packs, are fairly thin so they don’t stay frozen on their own for every long but a few together or in the cube shape do keep sandwiches cold for well past lunch time, not all day cold tho.
