Classic porcelain gets an update with this new double wall construction! Although you will enjoy admiring the fun, uplifting design of the Canteen Double Wall Porcelain Cups, 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. They will also keep cold contents chilled longer. Each Canteen cup features a colored silicone, non-slip grip for secure handling. With a multitude of cheerful colors to choose from, we invite you to switch up your daily routine every day of the week! Set of two 3 oz. cups. Also available in 3 oz. and 6 oz. sizes.
