Campus 彈蓋水瓶 600 毫升 - 野馬

I've been putting this bottle in my backpack every day for two weeks and not a single drop has leaked, even with sparkling water in it. The button release is smooth and the cap clicks shut with a satisfying snap, plus I just toss it in the dishwasher when it gets grimy.

The flip cap stays up just perfectly while I drink, which is way more convenient than I expected. It’s survived two weeks of daily jostling in my backpack without a single leak, and the 600 ml size is spot on for a full day of classes.

The button mechanism feels solid—no wobble or accidental pops in my bag so far, and I love that it handles carbonated drinks without a mess. Threw it in the dishwasher after a week of daily use and it came out spotless, which is more than I can say for my old bottle.
