Campus 600ml フリップキャップボトル - Star Wars

The button flip lid is genius—I can drink one-handed while holding my daughter's hand crossing the street. Filled it with sparkling water and zero leaks in my bag. The click when it shuts is weirdly satisfying too.

My kid's been using this for a month and it hasn't leaked once, even tossed sideways in a backpack. The button release is easy enough for a 7-year-old, and I like that the cap stays up while he drinks. Fits in the side pocket of his school bag too.

The pop-up lid is oddly satisfying to click open with one thumb while I'm cycling, and it actually stays up so I can drink without holding it. Filled it with sparkling water and no leaks in my bag so far.
