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

Worked really well in my cooler picnic bag. They're small, meaning they're light and don't weigh the bag too much. They stay cold for a long time even when the ice has melted. Will continue to use as they didn't leak at all.

Probably more ideal for picnics. Definitely work and didn't pay a fortune so I'd say they are worth it. They do the job but are quite small.

I bought these for my son’s school pack lunch bag and they are great. Just small enough to fit and very handy. The lunch bag is still cold at the end of the day. You get 6 so quite a lot for the price and value for money

The size of a pack of cards and brilliant for lunchboxes.I also chuck one in my bag in a zip lock on the hottest summer days and use it inside my wrists on the london underground. They've made unbearable summer commutes doable again!

Worked really well to keep baby food frozen in a cooler bag while travelling. They are small sized, but that’s a good thing as you can just put more of them in as needed.

I thought that they were larger than they are however, still keep cans of drink cold in a coolbag

Use these for kids lunch boxes. Small size and fit nicely in lunch boxes.

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
