The 3-Way Out Tyvek Envelope by Bazz

With credit to Mark Chandaue, who also features the 3-way out envelope in his books Totally Free Will and Harpacrown Too.

• Size: Height 7.5 cm x 10 cm wide.
• Thickness: Kate Moss
• Material: Tyvek
• Color: Brown/light brown

How it works: One side opens to reveal two compartments; the other side is normal (3 in total). Open it up, tip out the contents into the participants’ waiting hands. Job done.

• Can the envelope be shown empty? – I wouldn’t do it. The envelope was designed to be opened, accessed, and emptied into the participants’ hands within seconds. This should leave no doubt in your helper’s mind that the envelope is otherwise empty.
• Can a Participant Open the Envelope? – “Yes” if you want to give away the secret and “no” if you want to keep the secret, well, secret.
• Can I waste the potential of this envelope by putting playing cards in it? – Not really; these were NOT designed with playing cards in mind. I specifically designed them for use with slips of paper to keep the envelopes thin and light, not bulky and heavy. But if you must, then try Phoenix Double Decker cards at your own risk.
• What glue do you use on the flaps? – Pritt Stick Temporary Glue Roller. This stuff rubs off easily, which keeps your envelope looking fresh. It’s also super easy to apply precisely.
• How can I keep the envelope looking nice? – Take good care of it, treat it well, buy it flowers, and every so often leave it under a heavy book overnight—this will keep it nice and flat and straighten out any creases or bends you may have accidentally made.
• Are they really tear-proof? – Yes, but don’t test this—there’s no need to. It won’t rip, but it will distort the envelope’s shape.
• Are they really waterproof? – Yes! So now you can perform safely in your local swimming pool.
