Unleash the detective within every time you enjoy a hot beverage with this officially licensed Heat-Sensitive Batman Mug. At first glance, the mug displays a sleek, black Batman emblem surrounded by bats. But as soon as you pour in your favorite hot drink, the mug transforms, revealing an action-packed collage of Gotham’s most infamous villains, including the Joker, Harley Quinn, and more, locked in battle with the Dark Knight. The exterior of this officially licensed 16 oz Color Changing Mug reveals the hidden image once hot liquid is added. Hand-wash only. Not dishwasher or microwave safe, as extended exposure to extreme temperature will damage the product. Hand-wash only.
