Nothing says Thousand Year Old Vampire like a pin that looks like a tiny Thousand Year Old Vampire.
The pin is about 1.5" high and has two pinbacks to secure it in place. It was made in China. It glows in the dark. Other than that I don't know what to say. It's not a pledge pin so I think you can wear it to your college ROTC and not be made to do push ups.
