Classic porcelain updated with double wall construction! Introducing our CANTEEN design silhouette in white porcelain injected with a flash of color. Although you will enjoy admiring the fun, uplifting design, its function is what will make it your favorite daily cup of choice! Double wall design enhances the function of a traditional mug by adding thermal properties keeping the temperature of hot beverages hot for a longer period of time while remaining cool to the touch and will keep cold contents chilled.
