Klassieke Tumbler

The double-wall insulation is no joke—iced coffee still had ice cubes after a four-hour drive, and the outside stayed completely dry. Both lids screw on snugly, so I can toss it in my bag without worrying about a mess. This is the only cup I reach for now.

I’ve been using this tumbler every morning for a week and the double-wall insulation really does the job—my coffee’s still warm at noon. The straw lid is super convenient for sipping while driving, and not a single drop has leaked in my bag.

The flip lid snaps shut with a satisfying click, and after leaving iced coffee in the car for three hours, there wasn't a single drop of sweat on the outside. Double-wall insulation really does its job.
