마블 클래식 텀블러

Dropped it in my bag with loose keys and a water bottle, and the double-wall insulation kept my coffee hot for a solid four hours on a cold commute. The straw lid clicks on securely and hasn’t leaked a drop yet, which is more than I can say for past tumblers I’ve owned.

The flip lid seals tight enough that I tossed it in my bag without a second thought, and my coffee stayed hot past lunch. The pat pending on the straw lid is a nice touch too since the twist seal actually holds.

Took this tumbler to work and the double wall insulation actually kept my iced coffee cold through a whole shift, which is more than I can say for my last cup. The straw lid clicks on securely, and it fits right in the car's cup holder without wobbling.
