Such a lovely and handy product So lovely and sleek

Now I want one for myself.

I got my (adult) brothers these for Christmas last year as they carry their lunches to work. The ice pack is small but super sleek and I think they both appreciated the fact that it didn't look like something you'd find in a kids lunchbox (not that I think there's anything wrong with that, but for some it might matter). The price is on the high-side, but I can't imagine ever needing to replace it.

perfect for school lunches

This is a wonderful ice-brick for school lunches. It is small and light and will even fit inside larger lunch boxes. I like it because it's very easy to clean and is not plastic. With no cloth or polyester wrapper all that is needed is a simple wipe over. I'm very happy with the purchase, so much so I think I'll buy one for my own lunches! When taking it out of the freezer though you need to be careful your hands are dry!

Handy size and durable!

I purchased 6 of these last year. They are fab! They are much smaller and more slimline than traditional ice packs, which makes organising packed lunches much easier. And I prefer these to liquid filled pouches, as they tend to wear out eventually whereas these are very solid and are showing no sign of wear after a year of use. Onyx products are very well made and durable!

Nice and slim line

Fits well in my handbag with my lunch container. Holds temperature pretty well. Will be buying more.
