Perfect Match Dlx (4712)

This is a real mental magic. There is a Perspex frame on which ten cards with different shapes are placed at random.

Remove all the cards and give five of them to an audience to shuffle and keep the rest for yourself. First place your cards on one column and then ask your assistant to pass every card one at a time and choose where you have to place his/her card. At the end of it, the audience finds all the ten cards have perfectly matched two by two.

A really perplexing item to amaze your audience.
