Campus 保溫瓶翻蓋式 350 毫升 - 酷薄荷

The flip-up lid seals perfectly in my backpack without a single drop leaking, and the 350ml size fits nicely in my lunch bag. The cool mint color is exactly as fresh as it looks in the photos, and the bottle stays cold for hours during class.

The flip-up lid is so convenient for one-handed drinking between classes, and the cool mint color looks even better in person. It's been completely leakproof in my bag, and my water stays refreshingly cold for hours.

Took this to class every day for two weeks and the water stayed icy cold from morning till last bell. The flip-up lid seals tight enough that I've tossed it in my backpack without a single leak. The cool mint color gets compliments constantly.
