This prop is for mentalists in particular, and those who want to force objects in the CLEANEST possible manner. We have happened upon what is most certainly the FINEST, MOST LUXURIOUS, and CLEVER forcing folio we have ever seen.
In short, "Force 4" allows you to force four of ANYTHING in the cleanest possible way. As just one example, you can present four envelopes and have them freely shuffled and laid on top of your portfolio pad. The spectator is then allowed to choose ANY envelope. Without so much as touching the envelopes, you can offer the same free choice of ANY envelope to three more spectators. Despite all this, you control the outcome of EACH choice. If you are looking to perform a chair test, multiple prediction, lottery effect, wardrobe prediction, or any number of effects, "Force 4" is a treasure trove.
There are other forcing portfolios, and we have carefully examined all of them. THIS on—"Force 4"—is the best one, and therefore the one we recommend to you.
