2 x Set of 3 Mini Ice Brick Pack Block Blocks Freezer Cooler Bag Box Travel Picnic (Assorted Colors)

Great size for sandwhich bag stays cold for about 5 hours in cool bag picture against 2 aa batteries to give you idea of size

These are perfect for lunch boxes just the right size. I haven’t used them yet but have used similar size ones in the past so know they should stay frozen until lunch time. After reading other reviews and questions one question that came up a few times was is the filling non toxic. As you can see from the photo the packaging lists sterile water and I presume all the colours are the same. They all seem well sealed as well so should not leak.

Great little coolers, size around the palm of my hand and 3 of them mean that you can layer them in between Tupperware dishes to keep a few things cool at the same time. Tested during the height of summer when there was no fridge space at work and they kept my sandwich, fruit pot and can of fizzy cool. They work more effectively if in an insulated bag or similar. I would buy them again if needed, but they have lasted a couple of years already, so not sure if I will have to replace. Well made and robust.

I like that the ice packs are small enough to fit into lunch boxes. We all take packed lunch boxes to work and school and I feel better knowing that yogurts and dairy based items are being kept cool till lunchtime when using these.

These ice packs are a good size and are sturdy (so hopefully won't burst - especially because I use them to keep an 8 month old's food cool while out and about). We have used the foil ice packs before but find that they do tend to burst overtime so we now prefer to use these despite the extra space they take up in our lunchbox. They are very effective at keeping the food cold and I would recommend them.

only used these once, and combined with my cooler lunch box, kept my already cold drinks cold for several hours - will use again soon though to test again, as i am still unsure how long they will actually last, given their size, so might buy a bigger ice block to use with them

At first I used mine in a lunch bag, to keep my snacks cool. They last OK but by 1pm, when I start working at 8am, they're getting warm, but know I use them to chill cans of drink, they're excellent.

These three small ice packs are perfect for keeping snacks and lunches cool inside a lunchbox. They aren't very big but are perfect and light for picnics. Excellent value.
