You will get
Without any suspicious moves at all, you can immediately cause a signed card to appear in the card case. Your spectator will watch in disbelief as with empty hands you fairly pick up the box (nothing palmed), show the box on both sides (nothing to see), genuinely un-tuck the flap (the box is really closed - always has been) then slowly and fairly remove the signed card from inside of it. YES! THEY ACTUALLY SEE THE CARD COME FROM INSIDE THE BOX!
In late 2011, Dave Forrest received a link in his inbox pointing at a short video of a 'card to box' concept. The sender was Kevin Schaller and the video fooled Dave badly. Dave took Kevin's initial concept and made additions to the gimmick making it more practical for the real world and, through constant use, began to unearth the true depth of Kevin's discovery. XBOX was born.
Yes, you can very easily have any card arrive in the card box but this is not just a simple 'card to box' routine. It is a utility gimmick - a system - that will also allow you to seamlessly switch cards in the box for cards in the deck. So, you can show a card inside the box at the beginning of the effect then secretly switch that card for another during the routine! Imagine the possibilities!
