Another Invisible Mark by I-Magic

The magician shows 4 cards, each card has the same red-back.

He says he is going to reveal the secret of how magicians secretly mark the cards to find out which card is which…



However, the spectator cannot see the marks… because they are invisible…



Now the magician makes a magical gesture to make the invisible marks visible…



One at a time, the secret invisible mark changes into “visible” marks…



All cards have been exposed…



But here comes an extra surprise…



The “heart” is NOT just marked on the card. There is an actual open hole in it!!



This item has been performed at F.F.F.F. convention by Hayafumi and is critically-acclaimed!!
