It's a bird! No it's a plane! It's a..a...oh yeah, you're right. It is a plane. We just love our new airplane mug. Perfect for travelers or pilots or hey, even just for someone who likes planes. All of our mugs are hand-thrown in stoneware clay and hand-painted. This piece was hand-dipped in our lead free Williamsburg Blue glaze and holds approx. 14 fluid ounces. As this item is hand-made, please recognize that no two mugs will be exactly alike. That's the best thing about handcrafted items! Microwave, dishwasher, and food safe. Avoid extreme changes in temperature and do not use on the stove/on an open flame. Proudly hand-made in the heart of the Poconos, PA, USA. Materials: Ceramic
