Ellipse 保溫瓶 500 毫升 | 17 盎司 - 北歐黑

I've been using this for my morning coffee commute, and it's still pleasantly warm after my 4-hour work shift. The fact that I can also put carbonated drinks in it without issues is a nice bonus.

Took it on a three-day train trip and my coffee was still steaming at hour ten, which honestly shocked me. The lid seals tight enough that I tossed it in my bag with sparkling water and not a single bubble escaped.

Took this on a long train ride and the coffee was still properly hot twelve hours later, which honestly surprised me. The 500 ml size fits in my bag’s side pocket without sticking out, and the lid seals tight enough that I even risked a fizzy drink on the way back.
