De Black Tyvek Himber Envelopes zijn een geweldig hulpmiddel in poker card grootte. Het zijn double sided himber enveloppen in zwarte kleur, gemaakt van een duurzame tyvek materiaal.

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 10 black Tyvek envelopes. No instructions included.
