Bình Giữ Nhiệt IceFlowTM Ống Hút Lật | 40 OZ

The flip straw is the reason I grabbed this, and it doesn't disappoint — no more hunting for a separate lid when I’m rushing out the door. It slides into my car’s cup holder without wobbling, which makes my morning commute way less stressful. Ice still clinking around after a few hours is the best p

Finally a tumbler that actually fits in my car's cup holder without wobbling, and the flip straw mechanism seals tight enough that I can toss it in my work bag without a drop leaking. I've been using it all week and the 40 oz size means I'm not refilling every couple hours, which alone is worth it.

I was skeptical a 40 oz cup would fit my car's cup holder, but this tumbler slides right in and the flip straw is super convenient for driving.
