Thermos Super Light Travel Tumbler 470ml Rose Pink 3 "Use with care. Excellent for retaining cool or heat!" Kathryn 26 November 2019 This is a sleek product, very lightweight and easy to transport in rucksacks and car cup holders. It keeps fluids cool and hot, VERY hot. So be wary and don't scald yourself. Also, there is a flaw in the design which, if using hot liquids, I urge you to be careful as when tipping the flask to the mouth it collects in the rim and rushes out missing the mouth particularly towards the end. So twist off the rim along with the lid or take a cup.
