The effect is incredibly simple and VISUAL… Just the way magic should be! Four blue backed cards are shown and one by one they turn face up, then with a snap of the fingers the backs change to multi coloured. Incredibly visual & stunning. Very easy to do. Instantly reset! \”This is one you just have to have… I promise you, you won\’t regret it!\”– Gary Jones and Magic Tao \”…the best packet trick ever\”– Chris Webb
