Your spectators eyes will litterly pop out of their heads! I know because I used to perform this trick using these very cards all the time.
You show a perfectly normal pack of cards. In a flash the cards now have blanks backs, a tap and now the fronts are blank as well, all the cards blank on both sides! What can be done? You cant do tricks with blank cards. No bother for the ultimate card ninja – one simple cut of the deck and bam! all the cards are back to how they started, printed on both sides. An impressive routine, made simple with this ingenius set of custom printed playing cards.
