This is the original set of Jumbo Twisted Sisters that was produced by A-1 Magicalmedia. It includes the eight necessary cards in Jumbo size with Bicycle backs, an instructional booklet, and an additional instruction sheet. Very few of the originals are available.

If you are not familiar with the now classic effect: Without touching the cards, the performer causes two thought of cards to trade places in an exceedingly fair and magical manner. And there's more! Not only do the backs of the cards that transposed cards have different backs but the rest of the cards are now shown to be blank.

This is a warehouse find and there are very few in stock.
