While at first it may seem like an ordinary brush, our Bottle Brush is a 2-in-1 cleaner. (Cue the oooohs and ahhhhs.) The brush itself has hundreds of germ-fighting bristles and it fits perfectly inside Owala bottles - making scrubbing easier than ever. Plus, the brush head is removable and dishwasher safe. But here’s where things get exciting: there’s a flexible, Twist-n-Hide straw inside the handle that will keep your straws squeaky clean. It’s pure magic.
