Review on 853240, stainless steel by Momchil Kinov ᠌

Simple structure. When it comes to my model, the cork has a small elastic gasket that is screwed along the thread. There are no buttons, valves, or other mechanisms of any kind; in order to pour it, all you need to do is unscrew it a little bit. The only time you need to completely unscrew it is when you are filling the thermos. The lid, from which you can drink, is nothing more than a simple opening. The airtightness is fantastic, and the temperature is maintained for a considerable amount of time.
