In their centuries-old folk art tradition, our artisans in Brzeg, Poland create this St. Patrick's Day ''Caitlin'' bubble mug. To craft each one, two groups of artisans work side-by-side: those who form the shapes of native clay, and those who adorn them by painting blue and yellow flowers, green shamrocks, and ladybugs with carved sponges and fine brushwork. The unique properties of the clay and the high temperatures at which it is fired create kitchenware that is safe for the dishwasher, freezer, oven, and microwave. Handcrafted exclusively for Uno Alla Volta, from the heart and hands of the artisan. Dimensions - 3.5'' tall, holds 11 oz.
