Tupperware® 經典大 T 隨行杯 | 37oz / 1.1L

The lid seals tight enough that I can toss it in my bag without worrying about leaks, and 37 ounces means I actually hit my daily water goal now. Ice cubes still rattling around after four hours in a warm car—impressive for a tumbler this size.

Finally stopped losing my water bottle in the car since this thing holds nearly a liter and I only need to refill it once a day. The lid seals tight enough that I can toss it in my bag without worrying about leaks, and it fits right in the cup holder despite its size.

Ice stays frozen for hours—I took it to a long road trip and still had cold water by afternoon. The only small downside is the wide base doesn’t fit my car’s cup holder, but it’s great for the desk.
