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

Done the job for school lunch bags! Great quality and a good size kept items cool until the end of the day! Would purchase again.

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.

No, I didn’t check the measurements - Yes I should have done. Is it a problem? Not really. I bought these in preparation for use with a cold air fan - that uses ice blocks/water for cooling. I wanted a smaller size ice block as I was concerned the usual size, the ones you think of in lunch boxes, may not fit. So, the smaller size is actually welcomed. These can still be put to use in my work lunch box, although I’d recommend putting 2 in an average size lunchbox for best cooling. I think 1 would struggle for good coverage given the small size. I can’t comment on the longevity of the ‘freeze’, as I’ve not used them yet. They look well made, and the wife is happy to put them to other use once the sun disappears once again.

Just the right size for a lunch box or a bottle

Smaller than expected but could just be me not looking right. Takes a long time to get cold enough for use. Works okay but for what I needed I had to buy something else

Excellent for lunchboxes Good value item Nice and neat Easy to re freeze

These are ace for daughters pack lunch at school. Keeps her lunch fresh. Had her friend asking for them. Not bulky at all and could fit in any pack lunch box.

I didn’t pay enough attention on the size of these but they fit nicely into a cool bag. Did not stay frozen for very long though when in a cool bag placed out in the sun for 6+ hours

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.
