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 super limited edition is zombified (standard with brown musculature and black brain). Eyes are blue with red irises unless special requests are made. There is also a non-zombified regular Limited Edition of 100 pieces.
