*ONLY ROGUES CAN GET THESE BY PICKPOCKETING HUMANOID MOBS*
These mobs can be found in the instances of Blackrock Depths, Blackrock Spire, Dire Maul, Scholomance, Stratholme. They can also be found on humanoids in Eastern Plaguelands, and on a few other scattered other mobs throughout the world.
I am paying 1g (OBO) per box because of the massive quantity needed or we can work out other arrangements as needed.
Message me in game if you have some you'd like to trade me, CoD.
