KEPLIN Freezer Ice Blocks (6 Pack) – Reusable Ice Packs for Cooler Bags, Lunch Boxes, Travel, Picnic & Camping – Long Lasting Cooling Gel Keeps Food & Drinks Fresh for Hours

Great little ice packers for everyday lunch at work💪

Good size freezer pack for lunch boxes etc. Stay frozen about 5 hours. Fast refreeze

Very good value for these freezer blocks. Would buy again if I should need more in the future.

Excellent purchase. I bought these freezer bricks to put in freezer hold alls when I was replacing my fridge freezer and needed to keep the food frozen they worked a treat . I also used them in a smaller holder to bring my beautiful little cats insulin home from the vets. They are very durable and versatile. The colour is fine and they are easy to transport out of doors. They fit nicely into outer bags and are easy to use and store.

I bought these freezer blocks specifically to help cool down my fish tanks during the recent heatwaves, and they’ve been an absolute lifesaver. Once frozen, they stay cold for a good amount of time. I pop them into ziplock bags and float them in the tanks (never directly in the water) whenever the temperature starts creeping up. They bring the temperature down gradually and safely, without stressing the fish. They’re reusable, don’t leak or sweat much, and freeze quickly—perfect for rotating throughout the day if needed. I also appreciate that they’re compact enough to fit around the tank without being bulky. If you’re an aquarium keeper worried about rising temps in the summer, these are a super handy, low-tech solution. Highly recommend!

works well for the price and convince of next day delivery. held temp well. size was decent, could have been larger due to the size of my colemans coolbox easy to use and sturdy

Silly question do I freeze straight away or do I need to change the water inside?? I thought they would be bigger but I didn’t read the size guidelines lol

Very small, adequate.
