Tramontina Exata 550ml 附蓋隨行杯，不鏽鋼

I’ve been using this tumbler every morning for my coffee, and the double-walled steel actually keeps it hot for hours—way better than my old plastic one. The 550ml size fits perfectly in my car cup holder, and the lid snaps shut securely enough to toss in my bag without a drop.

The blue color is even nicer in person, and the lid snaps on securely enough that I can toss it in my bag without worry. My morning tea stays hot for a good couple of hours, which is exactly what I needed for my commute.

The double-wall insulation keeps my coffee hot for hours, and the 550ml size holds a good amount without being bulky. I also appreciate that the blue exterior doesn't show fingerprints or smudges.
