well it's an old method from old books that used this gimmick as your back turn around you can see behind you, it's the exact same gimmick used for the "CIA by magic balay & the blue crown", plus you need to do some diy and prepare your business cards to gimmick your business cards or the cards that you'll receive in your package, I was disappointed, i thought that it was something else from the video description , I though that it was ready to use and much more clever, although he gives differents idea using it , actually you'll receive everything to begin performing it but some of them need more time preparing the gimmick and other ideas less time , he teaches using it with playing cards . At least the price is ok to all the stuff you get, I gave it 3 stars because it's not his original idea plus the gimmick isn't perfect(not smooth & clear), and the spectator need to draw/write on the half of the card , meaning the spectator hasn't the freedom enough , in my opinion there's better Gimmicks and better way using your business cards with out any Gimmicks only little bit of sleigh of hands
