Tyvek Himber Envelopes are a magician and mentalist's dream!

Alan Wong's Tyvek Himber Envelopes are a double-sided, poker-size himber envelope made of a super strong and durable brown Tyvek material.

They can be used for a variety of applications such as:

  • Switching any freely chosen playing card with a force card
  • Revealing any one of two force cards as a prediction
  • Using two double face cards in one envelope to create four possible outs
  • Using blank cards for multiple force words

Combine them with Alan Wong's Universal Switch Device for even more possibilities.

Each pack includes 10 Envelopes. No instructions are included.


Customer reviews for Tyvek Himber Envelopes



If you are a mentalist or even a magician, I feel two way out envelopes ought to be a tool that can easily improve an effect somewhere in your repertoire or allow you to create and explore new effects that weren't possible before.

The fact you get 10 of these in a pack and they are made of Tyvek means you will be able to use these for a very long time. The design is highly deceptive and allows you to reveal any out you want just by turning the envelope over. That being said, the design is slightly flawed as the envelope flap sometimes opens up slightly as it does not properly tuck in, a minor flaw that shouldn't really impede the effects you will perform with it.

Bank Night, Kollosal Killer, Prediction Effects, Card to Envelope and so much more can be accomplished with these two way out envelopes, if you want to buy a sturdy and reliable pack of them, these are certainly a good place to start.



The envelopes are not bad.
But the price for 10 is very high.
They can hold a maximum of 2 Cards per side. If you insert more it doesn't close well. Then the cut of the closure of the envelope is too low, if you are not careful it opens. Overall, it is a good exchange bag for mentalists.

    • Rick asks: Are the envelopes reusable? Do the flaps (both sides of the envelope) stay completely shut until reveal time? (ie: using magnets, etc, which would also make the envelopes reusable)

      • 1. Dottore answers: Yes. Yes, as there is a slit that you can tuck the flap into.
