I got this because I was looking for a simple additional trick I could do with ESP cards I was printing myself for a different trick. This trick looked cute because the cards look so simple.
Without giving anything away, let's just say that EVERYTHING here is heavily gimmicked. This is in no way impromptu or as simple as it seems.
To make this, you will need supplies that some of you may already have, but this requires supplies much more specialized than say double-stick tape.
If you have or are willing to get the supplies needed, then I suspect the trick will play just as on the video.
But if you're looking for a simple trick with just simple ESP cards, there are many other tricks you can find.

As the product tag line suggests, there is some simple, one-off preparation involved (which does require a specific magician's gimmicking product), so you may have to spend a little more money (and wait for the post to arrive) before you can perform the effect. That notwithstanding, the method is extremely simple and clever, and the gimmicks are both in plain site and completely invisible throughout the performance. Even with the 'extra something' you might have to buy, I don't hesitate to give the effect 5 stars!
