After performing a series of card effects, the performer begins to shrink a fan of cards. Just a light squeezing motion, and voila! Cards have diminished by 25%! This is repeated four times until the performer is holding a small fan of cards 1/4\” in size! Finally, the cards vanish completely! Viking\’s Diminishing Cards are professionally used the world over. They are made to exacting standards and will give you years of service. Each set is hand-sewn, and hand assembled for the perfect fan; easy to operate. Complete instructions included. Mechanical, no difficult sleights. Recommended by Jeff Sheridan, Card manipulator, as well as professionals the world over. These cards are die cut for precision; each fan is a real fan of cards, not a cut-down version of poker cards. PLEASE NOTE: These cards are made by Viking Manufacturing and they are the absolute best of their kind. They no longer come in the black box on the picture, but instead they come in an envelope with instructions. This, of course, does not affect the way the cards themselves perform.
