Is not as fancy as the one-hand closure, but stays tight and the liquid hot longer. The thing is, with the Einhandverschluessen that does not stay tight, especially if the liquid is times thicker. As closure for the flasks (Isosteel VA 9553QAT flask 1.0 L, 18/8 stainless steel, ...) ensure always a better choice! Can also pour out without all the shutter open, loosen enough and it has the same effect! Locate the part with only 12 to 13 euros difficult overpaid that can not cost as much as half the bottle. The price is a joke!
