Campus gourde avec bouchon à clapet 600 ml Little Dutch - Fairy Wonders

The click-to-close button is oddly satisfying and it actually holds fizzy water without leaking in my bag. My daughter refills it herself since the cap flips open with one press.

The lid stays up on its own while my son drinks, which means no more fumbling to hold it back. It's survived a few drops on the playground and hasn't leaked in his backpack once. Fizzy water in it too, no problem.

My daughter figured out the push-button on the first try and now she won't put it down. The cap stays flipped up while she drinks so she isn't fighting with it, and it hasn't leaked in her backpack once.
