Nicholas Einhorn is one of the most trusted professionals in magic.
You receive two markers: a normal one that can be used to sign cards and bills and anything else during your show. The custom-made prop you receive works like a bill tube. You can load it from your back pocket, breast pocket, or simply from the waistband of your pants. No jacket is required. Nicholas performs the routine in conjunction with a classic bill switch, but this is completely optional. You can do this effect as a stand-alone piece, or use it with any bill trick you already do. The reset takes only a few seconds.
It is suggested that you use this trick as a closing piece. It's extremely powerful, and it is meant as a closer.
