After a long dark day of kicking butt at the office in Gotham City, even our masked vigilante needs to unwind and throw back a few at home. Alfred, however, will have no water rings in the bat cave. So, quickly dispensable from the utility belt is….. a bat coaster! Good for keeping a cold one off the finer things. This is a variation off my dark knight magnet. Coaster is 3.5 inches in diameter with a total height of .3125 (.25 thick with a .0625 thick rim). Enjoy!
