The Superman Costume Plastic Travel Mug gains super powers when exposed to…um…coffee! Yes, the “Man of Caffeine” yearns to protect the modest citizens of this Earth and uses his extraordinary powers in this regard. Oh wait, you know DC Comics’ Superman by something else? The “Man of Steel”? I think that was just for publicity reasons…his real power is an over abundance of coffee! The yellow sun thing is all smoke and mirrors! Joking aside, this great Superman Costume Plastic Travel Mug is in the likeness of the Man of Steel and will probably give you super powers. Just make sure that coffee is strong enough! (DO NOT MICROWAVE)We suggest hand washing!
