The Effect copied from the ad:
A red-backed Ace from one packet changes places with a blue-backed Ace in another packet.
The selected Aces appear face-up in each respective packet. Then their backs prove to be different. As a final climax, all of the other cards are shown to be blank!
Everything is examinable. Perfect for mentalists, table-hoppers, and card magic enthusiasts!
Step-by-step DVD instructions and a photo-illustrated e-book illuminate the workings of Duplicity. All necessary cards, specially printed by the U.S. Playing Card Co. are supplied.

Review
If you know Twisted Sister by John Bannon you know what a great packet routine it is. The multiple climaxes is what I love most about the effect. That and the simplicity. Duplicity is just like Twisted Sister but everything is examinable at the end. No switches. Basically there are no moves. Some word play is used but done very well. It is very easy to learn and perform. Some practice will be needed with your patter to perform it smoothly. It is a good price for something you can actually use. I really like Twisted Sister, and never had a problem with the fact that it is not totally examinable. In that respect I can't say I had a real need for the cards to end examinable. But I like the fact that they are in Duplicity. If you already have Twisted Sister, then you can determine if the examinability is something you want or not. I think I will use them both still.
Overall Highly Recommended 9/10
