Au Gold サーマルコーヒーカップ

I’m honestly impressed that my coffee stayed piping hot through a whole morning of back-to-back meetings — that 4-hour window is no joke. The vacuum seal keeps the outside cool to the touch too, which is a nice bonus.

Took the stainless steel body to a long bike ride and my tea stayed properly hot for the full four hours, which honestly surprised me. The vacuum insulation does exactly what it promises, and the gold finish looks sharp on my desk afterward.

My morning commute coffee is still steaming when I pull into the parking lot, which is exactly what I needed. The vacuum insulation really holds up—I’ve sipped for a full hour and it barely cooled. Definitely my new go-to mug.
