Kambukka Olympus 300 ml Jet Black,

With Olympus, logic is queen and simplicity is king. Its switch lid assures a smooth drinking experience and the clever design makes sure your activities don’t get interrupted by a leaking bottle. The Olympus coffee mug keeps your drinks both piping hot up to 6 hours (300 ml) or 10 hours (500 ml) and ice-cold up to 11 hours (300 ml) or 20 hours (500 ml).
Thanks to the Snapclean® technology, cleaning your bottle is easy peasy: just pinch and pull to remove the inner mechanism in one piece. By the way, the lid is dishwasher-safe!
