SWITCH-A-LOPE by Arnaud

THE Ultimate 4-way-out envelope 

Imagine an ingenious envelope that will deliver the correct prediction, no matter which of 4 possible outcomes occurs! YOU ARE COVERED! 

Every mentalist needs a 4-way-out envelope! There any many available, but none allow you to do the following:

Have the envelope signed
Keep the envelope in full sight during the show
Have the spectator take out the prediction
Show the envelope empty
Have a large folded sheet of paper in the envelope
No Slits, etc. 
SWITCH-A-LOPE by Arnaud allows you to do all of the above!!
