Magic Ludo

Magician shows 6 cards to audiences.
Each card with different pictures.
An audience choose a card and put it on table with face down.
Thus, magician does not know which card has been selected by audience.
Magician, then, put 6 dices into a box randomly.
The 6 faces of the dices have 6 pictures that same as the 6 cards.
Then, magician closes the box.
Magician holds and waves the box.
Magically, all 6 dices with the same picture face up.
And, the picture is same as the audience selected card.
