This package includes about 30-40 specially printed cards (half blue & half red backed) and the instructional DVD is very easy to follow.
It lost a star for me only because they come in two kinds; I mean that there are only two different combinations of cards fused as one.
Losing a star in this case is purely because I do strolling and there happens to be a lot of regular visiting guests who cannot see this more than twice.
Other than that, if this routine was done at a paid private show, I would probably close the show with it. The routine is a screamer.
In my selfish preference, I wish the refill package came with more combinations of cards rather than these two.
