Bioluminescence Mug


When the sun comes up in morning, that's the cue for twilight zone creatures at the surface to descend back to the safety of the ocean depths. Watch seven animals do their disappearing act while enjoying your favorite hot beverage! This 14 oz. mug is crafted with heat-sensitive, dishwasher-safe ink, but please don't put it in the microwave.
