Chai nước thủy tinh có vạch giờ DailyDOSE

The time markings on the glass are subtle enough that they don’t look like a gym prop, but bold enough that I actually check them every couple of hours. I’ve already finished my third refill by lunch, which never happened with my old bottle.

I was skeptical the markings would survive regular washing, but the glass surface stays clear and the times are still perfectly legible after two weeks. It's heavy enough to feel solid, yet the shape is comfortable to carry around the office all day.

The time markers on the side are a game-changer—I catch myself glancing at the bottle and realizing I'm way behind schedule by 2 PM. It holds up great in my bag all day and the glass cleans easily, though I do wish the markings were etched instead of printed so they'd never fade.
