保温ボトル Ellipse 500 ml | 17 oz - ビビッドブルー

I wasn’t expecting a water bottle to handle carbonated drinks without leaking, but this one seals perfectly even after shaking. The vivid blue color is even brighter in person, and it keeps my iced coffee cold for a full workday.

Brought this on a 3-day train trip and my tea was still steaming when I cracked it open the next morning. That 12-hour heat retention is no joke, and the vivid blue makes it easy to spot in my bag. Also handled a fizzy soda without any explosion when I opened it, which I didn't expect.

Cold coffee at 2pm after a morning commute? That's no longer a thing with this bottle—24 hours of chill is no joke. The vivid blue finish is also a nice pop in my bag, and the lid seals tight enough that I've thrown it sideways in a backpack without a drop.
