DC Comics - Flash Logo - Justice League - One 11 oz Morphing Mugs Color Changing Heat Sensitive Ceramic Mug – Image Revealed When HOT Liquid Is Added

While you wake up with a mug of coffee, the Flash will zoom (oops, how awkward!) around this heat-sensitive mug, making sure all is good. You might want to remind him not to go too fast, lest he start yet another timeline and throw your whole day off. Seriously, Barry. We’re sorry about that zoom comment. Please don’t erase our existence! The exterior of this officially licensed 11oz mug transforms from black as hot liquid is added, revealing the hidden image in full vivid colors.. PLEASE NOTE - Official Morphing MugsTM sold on Amazon.com should only ship from established sellers within the USA. Other mugs may be counterfeit. While this mug may be used in the dishwasher or microwave, for the longest lasting, highest quality product, we strongly recommend against it.
