I always knew that coffee was intrinsically connected to the Dark Side! The Dark Side is known for passion, energy, drive, and occasional erratic behavior...just like anybody after a couple cups of coffee! Zaaa-wig! The Star Wars Power of the Dark Side Ceramic Barrel Mug is a perfect vessel for your warm, caffeinated beverages and/or Sith Holocrons. Featuring Darth Vader on one side and the phrase, 'You don't know the power of the Dark Side', the microwave and dishwasher safe Star Wars Power of the Dark Side Ceramic Barrel Mug will help you strike down the Emperor and go into that creepy tree on Dagobah.
