These gimmicks are the most powerful tools a magician or mentalist can use. It is very difficult to believe that with such an inexpensive, unobtrusive gimmick, you can produce a staggering number of effects that look like real miracles. You can write letters, numbers, check marks, etc., surreptitiously--right in front of the audience--giving the impression that your message was written well before the event or effect took place. These gimmicks give you limitless possibilities. (2 mm. pencil lead. Each writer is refillable and includes a pin to help extract used lead. Also available with a grease marker tip.)
