Summit 兒童吸管蓋水瓶

My daughter drops this on the floor at least twice a day and it’s still perfectly cold after school pickup. The vacuum insulation really works, and I love that the straw lid doesn't leak even when tossed sideways in her bag.

My kid’s school bag has survived a whole week without a single damp spot inside, and the water is still icy cold by pickup time. The double-walled insulation is doing exactly what it promises, and the straw lid pops open easily even for small hands.

The straw lid truly is leak-proof — I tossed this in my kid's backpack sideways and not a drop escaped. Also, the double-walled steel keeps water icy cold even after a full morning at the playground.
