Review: Best Ice Blocks! - If you need to keep things to keep things cool in a larger food bag, these are amazing for picnics or travelling! They are well made. They are slim but effective! The largest board is impressive and works so well! They freeze quickly and stay cold for a good many hours . I was worried that the large one wouldn't fit in my freezer but it's so slim that it slotted in easily! The smaller ones might be a bit big for a kid's lunchbox but for keeping a bigger bag of food cold, they're amazing!
Review: Works well. Nice and space saving too. - These are very good, space saving because of their shape, keep things cool, just as intended.

### ⭐⭐⭐⭐ Effective ❄️❄️❄️
*by G***Y on 4 June 2021*

These are slim freezer blocks that fit comfortably into most cool bags and boxes. As such, they can be inserted between bottles and tupperware boxes to give maximum and even cooling. I use them in our Thermos 30l cool bag where they fit perfectly. They take about 3 hours to freeze solid in a domestic freezer. They do swell a bit in the process - but that's normal for blocks of this type. They are relatively lightweight but seem to be very effective. In a well stocked cool bag, they easily last for 6+ hours - even in a high ambient temperature (but don't leave the cool bag directly in the sun!). Thus far, we have no complaints ☺️☺️
