One of the best gimmicks ever created for Predictions is the Swami Gimmick, or Undernail Writer. The sky is the limit with such a Gimmick, because it allows you to secretly make a "prediction" long after it is supposed to have been made, and after the outcome of the event predicted is known to you. With just a modest amount of practice, it is possible to produce mind boggling effects with this simple gimmick.

We now have the gimmick produced in bulk. This is an adjustable gimmick, made of brass, to fit all thumbs and take various sizes of lead. 

Supplied in box of 50 gimmicks, prefitted with lead, and a 2 page "specimen instruction sheet" for its use and performance. Bulk of 50.
