Utility props with many uses.
Use one, two or three envelopes in a variety of mental effects. Three window envelopes, well constructed and printed, are supplied. Each envelope has been carefully assembled to hide several features indispensable to the thoughtful magician or mentalist.
For example, several versions of the venerable "Bank Night" effect are made possible with these envelopes. Also, the envelopes can be used for exchange effects, productions or vanishes, as each one has a hidden compartment built into it. Additionally, a set of envelopes that nest inside the larger, window envelopes are provided, multiplying your options for use.
The possibilities with these props are endless!
