Bottle Brush by CORKCICLE.

Fulfilled by our friends at CORKCICLE.

So fresh and so clean. 

Meet Bottle Brush. With a super scrubber nylon brush head, it gets the hard-to-reach nooks and crannies in your drinking vessel that conventional brushes might miss. Plus, it has an extra long, hangable metal handle to make cleaning all sizes of Canteen and Tumbler a breeze.
