Pour in hot coffee or tea and watch a Ravenclaw design bloom across this officially licensed Harry Potter 11 oz Morphing Mugs® Heat-Sensitive Mug. It looks solid black when empty, then the artwork appears as your drink warms the surface. Ravenclaw fans will reach for it every morning, and it makes a thoughtful gift for the Ravenclaw in your life.

Once warm, the mug shows a dark charcoal background framed by clusters of dusty blue flowers and thin gold stems. One side spells out RAVENCLAW in gold capital letters with a small star accent, and the other side features a large blue-gray bird in flight, its feathered wings stretched wide. Between them sits a cream Hogwarts emblem: a bold “H” inside a ring of HOGWARTS lettering. Near the handle, the artwork fades into a soft white haze. The blue-and-gold palette looks right at home on a desk or beside other Hogwarts house collectibles.

The mug is ceramic, holds 11 oz, and has a white interior. A heat-sensitive coating hides the design at room temperature, and the full-color artwork shows up as hot liquid warms the outside of the mug. When the mug cools, it turns black again, so the reveal happens with every refill. Hand wash only to help protect the specialty finish; the mug is not microwave safe or dishwasher safe.
