If you use Copin's style or system of thread work, this gimmick is a great thing to have in case the
thread breaks, and it will :), its a ingenious gimmick that allows you to get back into your hook
up, under the spectators nose, yes literally in front of them without them knowing. Its great that
it comes with a sample (about 3 feet) of Copins thread, for you to try out with your gimmick, and
because its not stripped, you can literally make 30 thread hookups to use with the ITS, even though
only one fits at a time. i got two ITS's just in case :)
