Spirit 紅酒杯

The vacuum insulation keeps my iced coffee cold for hours, even when I leave it in a hot car. The copper coating on the outside feels sturdy and gives it a nice, premium weight. I’m really glad I picked up this tumbler.

This tumbler keeps my coffee hot for hours during my morning commute, and I love that the copper coating really seems to help with the insulation. The double-wall vacuum seal is exactly what I needed.

I’ve been using this tumbler for a couple of weeks now, and the vacuum insulation is no joke—my coffee stayed warm for a solid three hours on a chilly morning. The copper layer on the outside gives it a nice grip, though I wish the lid snapped on a bit tighter for tossing in a bag.
