Made from 100% cotton, this black t-shirt features the symbol of the alien race, the Cardassians!  The Cardassians are a warlike race who are introduced into Star Trek: The Next Generation continuity and play heavily in Star Trek: Deep Space Nine.  They are tall, long necked and humanoid in appearance marked by bony protrusions and ridges lining the face and neck.  They aren't very friendly, and should never be kept as pets!  I would suggest not wearing this t-shirt in the presence of a Bajoran.
