Campus フリップキャップボトル 600ml - スティッチ

Filled it with fizzy water and it didn't leak a drop in my backpack all day. The click when the cap snaps shut is weirdly satisfying, and the flip-top stays up while I drink so it's not bonking my nose.

The button-flap lid is genius — I can sip one-handed while carrying my daughter's backpack, and it snaps shut with a satisfying click. It's survived a full week of being tossed in my bag without a single leak, though I haven't dared test the fizzy drink claim yet.

The click-cap actually stays up while I drink, which is way more convenient than I expected for a water bottle. It’s been tossed in my bag every day for a week and hasn’t leaked a drop. I even threw it in the dishwasher after a juice incident and it came out spotless.
