Every mug tells a story. "A Mother gives her child the heart to love and the strength to soar". Each mug starts as a solid color - as you add a hot liquid, the story unfolds, and the new image is revealed. The story mugs are made of high-quality porcelain, have a 16 oz capacity, and feature a unique square shape. Handwash only. Choose from Mother, Grandma, Sister, and Daughter.
