Tyvek Himber Envelopes BLACK by Alan Wong

Black Tyvek Himber Envelopes are great utility poker card size, double sided himber envelopes, black color, made in very durable tyvek material.

They are made for switching and multiple outs:

• Switch any freely chosen card into your force card
• Use any two force cards and reveal either one as your prediction
• Use two double face cards in one envelope to have four possible outcomes
• Use any blank card with any words, symbols and numbers for the above applications
• Force any prize, gift, prediction, bank night and any lucky themed routines

I use two of them in my Magnetic Himber Wallet and there are four outs but spectator sees only one envelope and one card.

Comes with 1 black Tyvek envelopes. No instructions included.
