Campus 保温ボトル フリップアップ 350ml - クールブルー

The flip-top lid on this 350 ml bottle seals perfectly—I’ve tossed it in my bag without a single leak. The cool blue color is exactly as pictured, and it keeps my water cold for hours during class.

I love how easy this bottle is to carry around school - the 350ml size fits perfectly in my backpack pocket and the cool blue color really stands out. It keeps my water cold for hours without any condensation on the outside.

The flip-up lid snaps shut with a satisfying click, and after a full 6-hour school day, my water was still noticeably cold. It's compact enough to slip into a side pocket, but the 350 ml capacity is just right for a quick rehydration break without being heavy.
