Have you ever been victim to the office mug thief? You know the one--the fishy employee that always leaves you mug-less when you are in dire need of your morning caffeine fix? Well, if so, I have just the solution!
The Plug Mug is a surefire way to get rid of the office mug bandit. Once the little plug is removed from the mug, there is a small little hole in the ceramic cup, making sure that no one uses your mug again.
The plug also has a key ring attached, ensuring that your plug is always handy when needed.
