Q & As

Rated 4.2 out of 5 by 22 reviewers.
Rated 5 out of 5 by Sleek and useful The product is very smart looking, but very lightweight and I worried that it would be too flimsy too keep water hot for the 8 hours as advertised, but it does so splendidly. It is so slim that it tucks down easily into my bag. 18 November 2015
Rated 5 out of 5 by Flask very light to carry around and easily fits in a handbag. handy size with a cup included as well. 06 October 2015
Rated 5 out of 5 by Very Useful I had been looking for a flask to keep my daughter's hot chocolate warm in for school.The other flasks had a push button design which was very difficult to clean and therefore not safe to use with hot milk. I loved this flasks simple screw top, it was easy to wash and keep clean. 06 October 2015

Rated 5 out of 5 by Great for one cup trips Needed a flask as I was travelling to London from Manchester on the train. Proved to be ideal as it had its own cup and kept coffee hot all trip. 08 September 2015
Rated 5 out of 5 by Just what I wanted! This does exactly what it's designed for.Keeping liquids hot or cold as required. 18 August 2015
Rated 5 out of 5 by Handy size I agree with a previous review about the super-stuck-on label but found a great tip on You Tube: heat the label with a hair dryer then slowly peel off and no glue is left behind. Tip to John Lewis though: why use super strength labels? 30 June 2015
