Aguamenti! Show your support for Gryffindor with this Harry Potter Morphing Mugs collectible. When you add your hot drink, the mug shows the Gryffindor scarlet, complete with an outline of a lion magically created with water and the Hogwarts crest. The exterior of this officially licensed 11oz mug transforms from black as hot liquid is added, revealing the hidden image in full vivid colors. While this mug may be used in the dishwasher or microwave, for the longest lasting, highest quality product, we strongly recommend against it.
