This is a mug shaped like a model of a human head used in anatomy classes with musculature shown on one half and the skull on the other. The heads have a magnetic eye and ear as well as a lidded brain with a straw hole. The limited edition comes in two color ways (standard with red musculature and pink brain or psychedelic with green musculature and blue brain). Eyes are normally blue for the standard version or orange for the psychedelic unless special requests are made. There is also a Super Limited Edition of 25 pieces.
