This is invisible thread that was manufactured for Fantasma Magic to include with its magic sets. It’s official name is “Secret Levitation Gadget.” The length of the thread is a healthy thirteen feet long and as in most of these types of ITs you can separate it into many, many strands of invisible thread.

The quality is pretty good as far as invisibility and strength is concerned. You will need to know how to separate the thread since no instructions are included.
