BLOOD is a system for applying secret markings to the back of playing cards that can only be distinguished by the performer and are invisible to the naked eye of the spectator.
The system has been developed from an old marking system once used by professional card cheats in the UK known simply as BLOOD.
The Blood Marking System covers not only how to apply the simple, overlooked and very easy to apply markings but how to utilise the marked deck to the best of its achievements and ultimately teaches performance techniques that allow any possibilities of the markings ever being spotted by spectator to be bypassed and never questioned.
Developed and designed to help the modern performer avoid spending a fortune on specially printed marked decks, The Blood Marking System offers a devious and simple idea that can convert your regular deck into the ultimate card-magicians tool.
