That's not a real sharpie. That's the uber rare medical sharpie. U use it to map ur beard (simply draw the arrows big enough for you to see in the mirror) before u shave. Then, as you shave, you remove the sharpie marks as you remove your beard stubble. Voila! You know you are done shaving when you can't see any arrows anymore. Ingenious really. Maybe I should get one....
