Even if the flasks are very cheap - I can not recommend it. After unpacking Been notches in the metal - well I thought to myself, You can accept this price. After I used it the first time, however, came the horror - all drinks from all thermoses taste like plastic and even after 10 times, determined wash by hand or by machine, the taste does not disappear. Seller did not respond to my e-mail; I have the thermos thrown away now. Too bad about the money!
