This officially licensed Harry Potter 11 oz Morphing Mugs® Heat-Sensitive Mug starts out solid black, then reveals a golden snake, the Slytherin name, and a Hogwarts emblem as your coffee or tea warms it. It’s an easy everyday mug for Slytherin fans and a thoughtful gift for Harry Potter collectors.

Once warm, the design shows a deep charcoal background framed at the top and bottom by olive-gold leaves and small cream flowers. A coiled golden snake with finely lined scales fills one side of the mug, and the Slytherin name appears in gold lettering with small star accents on the other. Between them, opposite the handle, the word HOGWARTS circles a large cream “H.” A soft white haze fades the artwork where it meets the handle.

The ceramic mug holds 11 oz, a comfortable size for coffee, tea, or hot cocoa. A heat-sensitive coating keeps the design hidden at room temperature, and hot liquid brings the full artwork into view as it warms the surface. When the drink cools, the mug turns black again, ready to reveal the design with your next refill. Hand wash only to help protect the color-changing finish; the mug is not microwave safe or dishwasher safe.
