In 2011, best girlfriends Tal Winter and Kate Cutler launched bkr with a focus on one main concept which in their minds was Beauty 101: drinking water is the foundation for soft, dewy, pretty skin. The clean, addictive, cult favorite, small-mouth, original glass water bottle was sustainable and eco at its core, but it also made drinking water blissful and easy for a change, and people started noticing. A growing obsession with the pretty little bottle resulted in reports that people were finally truly hydrated and, as a result, they were looking and feeling better. And, as it's said, the rest is history.
