As one comment said, it would be nice to know what did not work in his early use of the swami. But
the information given is gold. What undernail writer works, how to prepare it, how to fit it, how
to subtly get it on your finger (although that does require practice).
There are routines given
for its use, If they are not enough, look at Osterlind's other DVDs.
For those who criticize the
lack of routines, this is not something you will do an hour show on! This is a utility, a very
valuable utility, that, as a mentalist you need to know how to use.
If the undernail version is
not for you, try the Vernet Magnetic Boon writer or a band writer.
Richard Osterlinnd does
cover the various types of thumb writers on another of his DVD projects (Corinda?).
