Campus Isolierflasche mit Klappdeckel 500 ml Little Dutch - Fairy Wonders

The double-wall keeps drinks cold for the whole school day, even in summer heat. I tested it with sparkling water and not a single leak in the backpack, which honestly surprised me. That flip cap is so convenient for small hands, and the fairy print is adorable.

My daughter loves that she can open it one-handed while running to the bus—the lid stays put and there’s zero spillage in her backpack. The double-walled insulation keeps her water cold through lunch, and it handles the fizzy stuff without fizzing over.

The button-flip lid is so easy for my kid to manage, and it stays open while she drinks without dripping. Handles sparkling water fine too, which is a bonus since most of her bottles can't take carbonation.
