The idea behind this trick is good, but there is some fairly difficult slight of hand involved. It
is a decent effect but unless you are willing to devote hours and hours to making a dog tag go
through your shirt its not worth it. There are definitely better things that pack tiny and are easy
to carry all the time that are much easier to perform and generally better effects (loops for
example). I have put some serious hours into this and intend to polish it up but the effect on the
whole is not worth the money or the work.
