Klassieke Tumbler

Left it in the car with iced coffee for a whole afternoon and came back to ice still clinking around — the double-wall insulation really holds up. The flip lid snaps shut tight enough that I tossed it in my bag without a single leak.

I’ve been using this tumbler all week for my morning coffee, and the double-wall insulation really does keep it hot for hours — no sweat on the outside either, which is a win for my car’s cup holder. The straw lid clicks on securely, so tossing it in my bag has been leak-free so far.

The flip lid seals tight enough that I tossed it in my bag with zero worries, and the outside stayed completely dry even with iced coffee inside. My drink was still cold on a long car ride, which is exactly what I needed.
