The Kokoro is a sustainable porcelain thermal flask that leaves other bottles and flasks behind. Unlike metal bottles, the interior of the Kokoro is made of solid fine porcelain, which makes it stain and smell resistant, without that metallic taste you had to live with before, while keeping your beverage hot or cold for up to 8 hours with the help of its double-wall vacuum-insulated exterior. In contrast to enamel/ceramic coated interiors, or ceramic interiors, The Kokoro’s porcelain interior will not peel off over time, and will be much more resistant to stains and smells, due to porcelain being much less porous than ceramic.
