Screwed Deck - Paul Harris
Perhaps one of the finest opening effects ever created for card workers!
You show two halves of a box of cards and screw the box together, just like a pool cue! Unfortunately the deck will screw together no more and one half is the back of the box and the other half is the front. You then remove the deck inside, only to find out it's also half face up and face down! Give the deck one more EXTRA twist...it becomes an ordinary examinable deck of cards!
A visual and amazing card effect! Made in Bicycle poker size decks.
