"Cosmetic bottle, small size. This is not in the description but the cap is screwed and has a cleat that is calling and allows air to pour the liquid without unscrewing the cap. This is in two parts, not with two separate screws Consequence:. two places to shake that at the time of closing, or fluid leakage (which happens quite often even when I think I have tight, probably because the seal expands a little box of hot liquid after I closed the bottle). Moreover when it's this sort of screwed spout is very practical for daily use of the thermos. The bottle very careful hot and cold eg for my morning coffee poured boiling water in it is still burning hot at noon and correctly to 16h Small flat for the appearance. My usage is intensive but careful, yet the outer blue paint (actually a kind of coating film) started to come off in small pieces a few millimeters at the end of thirty days, revealing the metal underneath, and it will therefore continue. In the end I would say the thermos fulfills what is expected of him, but is a bit expensive due to small defects reported. "
