Mental Pen is Joao Miranda & Gustavo Sereno's modern version of an classic mentalists prop. Using a special Sharpie Pen, that's handled and fully examined by the spectator, the Magician can make a variety of predictions. As an example, the spectator can be handed the pen and asked to mark a cross on a playing card, a page of a book, or even a certain place on an image - The magician using the same pen, correctly predicts the spectator's chosen card, page or position.
