I've tried a few different invisible thread devices and tricks and this one is by far the easiest
and most inconspicuous I've come across.
The thread that comes with the pen is as near
invisible as it can be, but it's strong enough to hold up during effects.
The pen itself
looks like any old pen. The only downside to the pen is that the wax is quite visible if you have
the pen in a breast pocket or clipped somewhere. To combat this, I've just clipped the pen inside a
hoodie or jacket. It makes it a riskier because it's possible to snap the thread if it doesn't feed
smoothly, but with some practice it's not much of a concern.
The included explanation and
effects are great. Yigal gives great details and some very helpful pointers and tips during the
video.
I've been disappointed by previous invisible thread gimmicks but I'm really glad I
took a chance on the Spider Pen X. It's a bit expensive but I think it's worth it.
