In blackest coffee, in milk of white, no evil shall escape your sight! Whatever your choice of beverage, the Green Lantern Corps is here to support you, thanks to this temperature-sensitive mug whose decoration changes with what you pour in it. Hot beverages show one design, cold drinks another. Can Hal Jordan fight this battle alone, or is this a job for the whole Corps? Now you know how the Guardians of the Universe feel, as long as they don't feel thirsty. Microwave safe. Holds 14 oz.
