Review: Lasted 24 hour hot easy. - Excellent flask it kept our tea hot for 24 hours and didn’t leak at all, nice looking flask but wish it had 2 cups like our old one that we kept the cup from. £27 is the right price in my opinion. The flask is not too heavy when full and the handle is good quality too.
Review: Beautiful colour and great flask - I bought this flask as I was attracted to the raspberry colour. Flask came and I am happy with my choice. It is beautiful and water temperature retention is excellent. Finally have a good flask.

### ⭐⭐⭐⭐⭐ ncredible Heat Retention – Still Hot the Next Day, Great Value 1.2L Flask
*by T***E on 22 April 2026*

I bought this expecting it to be decent, but it’s genuinely blown me away. The heat retention is outstanding. I’ve filled it with tea at around 6am, forgotten about it, and then come back the next day at about 8am to find it still hot enough for a proper cup of tea. That alone makes it worth it. The built-in cup in the lid is a really convenient feature and makes it easy to use on the go without needing anything extra. It’s a simple touch, but very practical. The handle is a little fiddly at times, but it does the job and isn’t a major issue once you get used to it. In terms of value, I think the 1.2L size hits a great balance between capacity and price. It’s big enough to last all day (and then some), without feeling excess
