This is an accesory for you pencil. Not as clumsy or random as a ballpen or a keyboard. An elegant tool... for a more civilized age.
It will extend your pencil's life, while increasing its comfortability and your midichlorians too! ...wait, scratch the last one (or not?).
Of course, you can also use them to duel your friends/rivals/coworkers!
Just remember that, if you ever find your once mighty pencil's power fading, don't fear. Focus.
Use the force.
