Thread Reel for Invisible
The product is really well made and comes with enough string to last you for a while even after it breaks a couple times.
Easy to keep hidden, and thanks to the Invisible handbook I know how to restring it when the thread snaps (usually due to practice). Has plenty of thread as well and with enough practice it can be very versatile. -Needs- to get back in stock!
Definitely compared to cheaper ones, this one is way better for the quality. One thing I wish was provided with this purchase was an instructional on how to re-string the elastic string, as well as what type of elastic we should use.
