What you get is the clever gimmick, a silk that may not be the same quality as in the video, and a
link to some demos and instructions.
That the silk doesn't appear to be the same is
important. The one I received is a bit on the translucent side and that helps to reveal the method
when I'm pulling it through a phone. It isn't a sure thing that anyone would notice, nobody has
yet, but I don't see that problem "appears" with the silk used for the videos.
For me, the
videos were poorly done. You get to them with a shortened link. Mine was
http://m.site.naver.com/010lgq. (That wasn't the real link, just an example of what it looks like.)
That gets me to a video that I can't download. The seven minutes of instruction are poorly lit,
shot with a cell phone (I'm guessing), and narrated alternately in an Asian language, a different
Asian language, and occasionally a language that might be English. From the length of each
description it is pretty clear that aside from not being at all clear, the English speakers are
being shortchanged in the details department.
All that said, this thing is pretty easy to
figure out, even from what is provided. You really can make it look like you're pulling a silk
through just about anything. There is some setup but you can have that done ahead of time and in
your pocket (if you're very careful) or a performance case. Reset takes a second but needs to be
done out of sight.
It's a decent enough trick and I felt the instructions provided do a
disservice to people who chose to buy the "official" version as opposed to the many, far less
expensive knockoffs that are available.
