攜帶型保溫瓶（4-6週內出貨）

Took a gamble on the 800mL capacity since I'm a heavy drinker, and it’s paid off for my long workdays. The vacuum insulation keeps my coffee hot from morning to mid-afternoon without fail. The delivery wait was a bit long, but the flask itself feels solid and well-built for the price.

I was a bit skeptical about the 800mL capacity, but it actually fits my whole day's worth of water without needing a refill. The vacuum seal keeps my coffee hot for hours, even through my commute.

800mL is the perfect size for my long shifts—I can fill it once and have hot coffee all day. The vacuum insulation actually works, keeping drinks steaming even after eight hours in my bag. Definitely worth the wait.
