Klassieke Tumbler - Signature

Finally a tumbler that actually fits my car's cupholder without wobbling, and the straw lid hasn't leaked a drop in my bag after two weeks of daily commutes. My coffee's still warm three hours later, which is more than I can say for any other cup I've owned.

I was skeptical about the whole leak-proof thing, but I turned it upside down in my bag with coffee and not a single drop came out. The double wall insulation really does the job too, my drink stayed hot for hours on my commute.

Fits my car’s cupholder perfectly, which is rare for a tumbler this size, and the double-wall insulation keeps my coffee hot through my whole commute. The straw lid seals tight—I tossed it in my bag sideways and not a drop leaked.
