IceFlowTM フリップストロータンブラー | 40オンス - Stanley Create

The flip straw lid makes it so easy to drink one-handed while driving, and it still fits perfectly in my car's cupholder without wobbling. I've had it for two weeks now and it's become the only bottle I grab on my way out the door.

I’ve been tossing this 40 oz tumbler into my work bag every morning, and it fits the car cupholder better than any bottle I’ve owned. The flip straw lid actually stays shut in transit, so no leaks on my laptop. Ice still clinking after a full afternoon of meetings is exactly what I needed.

Finally got this for my morning commutes and it’s been a total game-changer—fits my car’s cupholder perfectly and the flip straw means I can sip one-handed while driving. Lid stays securely closed in my bag, too, so no leaks after three weeks of daily use.
