Each twin owls mug was handmade by our artisan JoAnn of the Poconos. She hand-throws each mug on a wheel, adds hand-cut details on one side, and then fires, glazes, and fires each one again. Her whimsical, hand-painted stoneware continually delights our team and her collectors. Microwave and dishwasher safe. No two will be exactly alike. Handcrafted exclusively for Uno Alla Volta, from the heart and hands of the artisan. Dimensions- 5 inches tall, holds 14 ounces.
