The instructional video has so many tips for performing it that it's WELL worth the price. The end
is such a shocker that it's a great platform to start the rest of your card act.
My one caveat
is that I don't agree that *everything* is examinable at the end of the trick. Since the deck and
the box both are, though, it's a wonderful opener. You do this trick, and while the folks are
reeling from the effect, you can start into your next trick with the same deck, leaving the box
right there on the table so that it can be examined.
I love this effect - this is my new card
set opener.
