(Demonstration shown with kind permission of Penguin Magic)

Exciting new card trick - "Sneek-a-peek" We have obtained a limited supply of sneek-a-peek from Penguin Magic in the States. When this is exhausted, they will again be unavailable to UK dealers, so please don't miss this opportunity to purchase this exclusive effect.

Effect: The magician displays a BLUE BACK deck and shows that ALL the cards have DIFFERENT FACES!! Now the spectator stops the magician as he genuinely and slowly riffles through the cards. YOU STOP EXACTLY WHERE THE SPECTATOR CALLS STOP! The spectator peeks at the chosen card.
NOW with your magic jokers, you now cause the following to happen:

ALL the cards change to the freely selected card.
The complete deck now has a RED BACK!!

No sleights, NO SKILL REQUIRED, no svengali or mental photography (blank deck) principles - this is FANTASTIC!

Remember, this is in limited supply and exclusive to emagictricks!
