This is a deck of thin, half-thickness cards. It contains 104 cards that look exactly like regular cards but are so thin that the 104-card deck is the same thickness as a regular 52-card deck that will fit inside any standard card case.

These are one-way forcing decks which means that the top 52 cards are all the same while the bottom 52 cards are a complete deck of cards that you can spread and show all the faces.

There are many routines possible by having cards selected from the regular half and forced from the top half. You can also spread the cards face-up to show them all different then turn the deck face down to spread the top 52 duplicates for a selection.

The back design is the now well-known Phoenix back and all the cards are marked for additional uses.

Includes one Phoenix Back, Double Decker, 104 Card Deck with 52 regular cards and 52 duplicates. Includes access to a tutorial that discusses some routines and ideas. Manufactured by Card Shark.
