The Superman Costume Ceramic Travel Mug mimics the look of the costume of DC's Man of Steel, Superman, on a ceramic mug with a handle and close-able plastic lid to prevent your drink from spilling while traveling! Maybe not flying, although Superman does have seem to have a remarkably steady hand while zipping from spot to spot. I mean, we've seen him carrying Lois (not to mention all manner of other things) while flying, and nothing's fallen out of her, right? Still, it's probably best to play it safe and only use this 6.5-inch high Superman mug as a beverage repository during ground travel. This Superman Costume Ceramic Travel Mug is pretty heavy and would hurt like the dickens if it slipped from your hand and fell on someone!
