Campus 彈蓋水壺 600 ml - 汪汪隊立大功 女孩版

The push-button lid is a lifesaver for my 4-year-old, she can open and close it herself and the cap stays up while she drinks. Fits perfectly in the side pocket of her school bag and hasn't leaked once.

My daughter drops this thing constantly and it hasn't leaked once, even with fizzy water in it. The button release is easy enough for her four-year-old hands but the cap stays clicked shut in her backpack. Removed the strap for washing and it went straight back on without a fight.

The pop-up lid is the best part, my kid can open it one-handed and the cap stays out of the way while she drinks. It's survived being dropped on the playground a few times and hasn't leaked in her backpack yet.
