Q & As

Rated 3.9 out of 5 by 16 reviewers.
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
Rated 5 out of 5 by Great product A very useful thermal flask that really keeps the hot fluids hot, for more than the 8 hours specified. Great value for money. 28 April 2015
Rated 1 out of 5 by Never even got to try it out - annoying sticker The sticky label on this flask was stuck on so fast, I gave up trying to scrape it off. I could have tried to soak it off, but I love sleek brushed steel products and inevitably the whole process would leave a visible mark. I returned to the store the following day and received a no quibble refund. Annoying though. 21 April 2015
Rated 4 out of 5 by Light weighted and good for every day use This is a quality flask.My daughter takes it for college and it holds enough soup for her lunch..It is also perfect for things like rice,pasta etc. She is Very happy and take it to college everyday. 10 February 2015
Rated 4 out of 5 by An ideal size flask This flask is an ideal size & keeps liquid hot a long time. 12 November 2014
Rated 2 out of 5 by Poor Lid/Cup The flask in itself is good , however when you wash the lid/cup water gets in between the outer and inner casing and it takes a lot of shaking to get the water out 31 August 2014
Rated 5 out of 5 by Thermal flask We bought this to keep our milk fresh for our tea in the morning as one morning the milk had definitely gone off by the time the teas made machine was ready. It does the job perfectly. 19 August 2014
