ミニカウベスティ ボトル 真空断熱水筒

Took this little cow flask to work and my coffee was still warm after five hours, which really impressed me. The double-wall vacuum insulation does its job perfectly, and the cute design gets a lot of smiles from coworkers.

The double-wall stainless steel body actually holds up in my bag without a single dent after a month of tossing it around, and that little cow face makes me smile every time I grab it for a sip. My iced tea stayed cold through a whole afternoon of errands, which is exactly what I needed.

The double-wall insulation really works—my coffee was still steaming hot after a four-hour hike. The cow face on the lid is way cuter in person than in the photos, and the flask feels sturdy enough to toss in my bag without a worry.
