Thermos King Copper Large Flask 1.2L 5 "fabulous!!" 25 November 2017 I bought flasks from an online site, they did not work and the seller would not reply. No help from them. This flask is absolutely fantastic. My husband is a farmer, so hot soup is a life saver. This flasks keeps it hot for more than 36 hours. He would like to say "thank you" ! . I should have bought from Lakeland in the first place.
