Doubts to the originality claims, but good demonstration of a common move. Subtleties covered with multiple angles. Great price.

I mainly bought Primary so I gain the concept of the sleight being used. But needless to say, this can have tremendous amounts of applications. And once mastered, this simple sleight can become invisible. I've played around with it for a while and I definitely recommend beginners (such as myself) to add this to your arsenal. It's a great color-change. Don't forget to practice though! Antonio, great job with the instructional video: It was very informational and covered everything I needed to know.
