CeraRing™
Pure Taste, Perfectly Preserved.
CeraRing™ is Calzone’s proprietary technology that combines the durability of stainless steel with the smoothness of ceramic. It preserves the original taste of your beverage without any metallic odor and ensures hygienic use. With a seamless ceramic coating that extends from the interior to the lip-touching area, it completes what makes the BOLD tumbler truly special.
Have you ever felt bothered by the metallic taste or smell when drinking from a stainless tumbler? With the BOLD Tumbler, that’s a thing of the past. We coated the entire interior with CeraRing™ ceramic lining—even the rim where your lips touch. This not only preserves the pure taste of your drink but also delivers a soft, pleasant feel against your lips. Experience the BOLD Tumbler: where taste, aroma, and touch come together for a truly complete drinking experience.
