Kokoro Thermal Flask has a solid porcelain interior

Editor's Rating

Want a reusable bottle that doesn’t stain or have a metallic taste? That’s the Kokoro Thermal Flask. Not only is this a beautiful thermal flask, but it also has a solid porcelain interior. Because it’s a porcelain flask, the Kokoro won’t taint your beverages with a metallic taste. Completely free of stains and smells, this bottle ensures your drinks stay hot or cold for at least eight hours. Available in 450- and 550-milliliter sizes, this bottle keeps you hydrated—or caffeinated—throughout the day. With an exterior made of 304 high-grade stainless steel, it’s entirely free of BPA. While you may be tempted to use stainless steel bottles for all kinds of drinks, some beverages don’t react well to metal. You can solve that problem and ensure great-tasting drinks all day long with the Kokoro. The company also provides a warranty for a one-time porcelain interior replacement if you accidentally damage it.
