Perfect for anyone who would like to enjoy a tea or coffee whilst out and about: the flip insulating mug 600 ml by Leifheit. This is 100 % liquid-tight and therefore completely leak-proof. It can also be quickly and easily opened with just one hand without the need to put it down. The push-button to open the lid can be comfortably operated using your index finger. An additional lock on the lid prevents accidental opening: so your mug can be taken about into your bag without needing to worry. The lid also has a soft-grip surface, which ensures a better hold and means it is easy to open. With the help of the fold-out handle, the flip insulating mug 600 ml is not only comfortable to carry, but also provides the option to attach it to a rucksack or bag. A removable filter retains any added ingredients to the liquid, such as herbs or fruit, and stays within the bottle without getting in the way whilst drinking. Thanks to the double-layered insulation made of stainless steel, drinks in the flip insulating mug remain hot for up to six hours and cold for up to 18 hours. With a capacity of 600 ml, it is perfectly suited to everyday use - no matter whether in the office, at university or in school. Naturally this mug is free from BPA as well as other harmful substances, therefore 100 % harmless. The blend of attractive stainless steel design and the fresh, fashionable colour light blue make the insulating mug a real eye-catcher. Also available in black, silver, dark blue, red, kiwi and purple.
