蛋白石真空保溫隨行杯

Took this on a six-hour drive and the ice was still clinking around that night, which honestly surprised me. The stainless steel body hasn't sweated onto my desk once, and the lid seals tight enough that I just toss it in my bag.

I’ve had this tumbler for two weeks now and the vacuum insulation is no joke—my morning coffee was still hot at 3pm after I got distracted at my desk. The stainless steel body also feels way more solid than my old plastic one, and it’s become the only cup I reach for on daily commutes.

Woke up early for a flight and brewed my coffee at 5am—by the time I landed three hours later, it was still hot enough to burn my tongue. The vacuum insulation is seriously no joke, and the lid seals tight enough that I just toss it in my bag without a second thought.
