G4GADGET 8cm Freezer Blocks Pack of 6 | Reusable Ice Packs for Lunch Boxes, Cooler Bags, Picnic, Travel, Camping & Outdoor Activities | Quick Freeze Design

They are really small! But did the job for what I wanted (keeping a cake cool in transit). Cute size, cute colours. If you’re after diddy sized cool packs they’ll do you just right.

Great for lunch boxes! Small and compact. Do the job :)

Silly me, didn’t look properly and these are smaller than I thought, wouldn’t have bought for this price in a supermarket. Seem fine though but probably not worth what I paid; thought they would be the equivalent of 3 normal size ones, definitely not

Perfect for what I needed. Nice small size

I bought these in the hope of using them in a cooler bag with breastmilk for flying long-haul. About the size of a square cigarette packet, these weigh approx 87gm so clearly contain less than 100mls of liquid in them.On a recent Trip from UK to NZ and AUS via Singapore, I never had any issues with security with these blocks! Most of the scanners were the new types where you leave your liquids in your case/bag at security, maybe due to it being in a cooler bag with breastmilk I never got questioned, but I had other liquids/pastes checked (baby food etc).I never had an issue with them leaking, they obviously don't have the same length of cooling capacity as your standard size freezer blocks, but they did allow me to fly with them so achieved their functionality objective.Good value for money, I'd recommend them for flying!

They are OK ish. The main problem is they are really too small to maintain the temperature. I have only used them once. I was out for a couple of hours shopping and by the time I got home most of them had defrosted. The only real use I found for them was on a hot day put a couple in front of an electric fan and instant "air con" for a while.

Have used these for a couple of months now. Walking to work in the warmer weather, these are so useful for keeping my lunch fresh in my rucksack. Nice and compact. Have not experienced any leakage which is great.

Handy size for portability. As expected does not last as long as the larger ones would but it comes in useful for fitting in a small lunch cool bag and for my uses - from morning to lunch- keeps the food cool nicely. I tend to use more than one at once.
