Lefty Princess Dribble Mug, Pink with Zebra Print Interior Imprinted with Lefty Princess on the front and warning on the back, "Caution Rightie You'll ruin your clothes LOL." Holds 12 oz. of liquid. Not dishwasher safe. Not microwave safe. The mug only works when held in the left hand. The graphics face the mug holder, and, more importantly, nothing will spill. When held in the right hand, liquid leaks out of a hard-to-see hole, dripping onto the foolish right handed drinker's clothes.
