G4GADGET Freezer Blocks Ice Brick Pack Block Blocks Freezer Cooler Bag Box Travel Picnic

Good to use if having picnics stay cold no leakage and decent size so fit well and good quality easy to use. Are light in weight aswell.

Hander freezer blocks for cooler bag. Just didn't realise they were mini when I bought them.

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.

They are very tiny so you’ll need many to keep the temperature down, they do work well especially if you have very little space.

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.
