Writers are one of the most powerful tools a magician or mentalist can use. These simple gimmicks allow the performer to do a staggering number of effects that look like real miracles. The performer can write letters, numbers, check marks, and so forth, right in front of the audience. This can give the impression that the message was written well before the event or effect took place. The possibilities are limitless. Bug Writers are specially designed to adhere firmly to the fleshy pad of the thumb. Their special design and sticky surfaces allow magicians and mentalists to write absolutely invisible directly in front of audiences. Note that this is the black grease pencil type of lead, which is the most visible version of the writer currently available. 0801RUMBUGWRITER_GREASE
