This looks like is was used maybe once.  Cards are clean and sharp.  Deck is specifically designed for one trick that you may be able to vary.  When you have someone pick a card from the NORMAL looking deck, they end up seeing you not only name (find) their card but you show them that you have "magically" made the entire deck into a deck of just thier card.  Simple and fun but a one off deck for one kind of trick.  Great for card beginners to build flip dexterity.
