bkr Tutu 500ml Water Bottle in Pink. bkr Tutu 500ml Water Bottle in Pink. Inspired by warrior women crisscrossing the globe in the name of fashion, slinking around London in trusty pink ballet flats, wearing them until they look like dirty Band-Aids, a Rossini-centric soundtrack in a store where everyone speaks with French accents, hair pulled back fresh and clean off the face, a sheer blouse with elbow-length sleeves and rose gold buttons. And it was just really an attempt to see herself with new eyes and extra colors, with no plans and no intention of arriving- just the knowledge that she would come back different from how she left.. In Tutu- Opaque Balled Pale Peachy Pink. Silicone seal with small opening for no-spill sipping.. BPA-free and phthalate-free.. 500mL/ 17 oz. BKRR-WA39. PKTTUPB-S16HT. 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.
