Klassieke Tumbler

I’ve been using this tumbler every morning for two weeks now, and the double-wall insulation really delivers—my coffee is still steaming at noon. The straw lid pops on securely and hasn’t leaked once in my bag, which is more than I can say for past cups.

The flip lid actually seals tight enough that I tossed it in my work bag with zero worries about coffee ending up on my laptop. Double-wall insulation kept my tea hot through a whole afternoon of meetings, and the outside never got clammy once.

Took this on a long commute and the double-wall insulation actually kept my iced coffee cold for three hours straight, which shocked me. The straw lid clicks on firmly and didn't leak once when I tossed it in my bag.
