12 dollars for this trick is a good price for a full, gimmicked deck. Now, that being said, after knowing the secret, these can be made incredibly easily yourself. Regardless, 12 bucks for what you get all-in-all is a great deal.

The effect itself is often discounted by magicians for being too simple; containing sleights that beginner magicians know. Regardless, this is still a trick that, although easy, still gets FANTASTIC reactions from laypeople. I highly recommend this routine, and don't let the fact that it is easy or can be made at home deter you from realizing the power of it.
