In Boleslawiec, Poland, Weronika and her team shape each stoneware mug from their native clay before hand-painting it with stunning floral motifs. Each is then high-fired. The large size is perfect for coffee or tea, whichever you prefer! Microwave, oven, dishwasher, and freezer safe. Handcrafted exclusively for Uno Alla Volta, from the hearts and hands of the artisans. Dimensions - 5.25'' tall, holds 18 oz.
