The Open Billet Box by Steve Pellegrino

Here are a few features of The Open Billet Box:

It folds up to fit into a briefcase.

It can hold a large number of billets.

The switch is silent.

Mechanically there is nothing to fail

In the manuscript Steve goes over the psychology of billet boxes in general and where the more expensive ones fail. He also includes two entertaining routines - one that you can use to open your show and one you can use as a finale.

Don't let the low price of the manuscript and the cost to create the box deceive you. This is practical, straight-forward mentalism that you will be happy to use in your show.
