I have reviewed this product on another forum. I do not recommend it for close-up or even parlor situations. The thread is too visible and simply not reliable. I even tried using a sharpie but that did not really work. Try V2 or mesika thread. They are worth the it...
I bought it because it seemed like a bargain, but any thread that is visible is useless. It ruins your magic.
Stay away, this is a VISIBLE elastic thread.

I was unsure about this thread because of mixed reviews, but at the price... I had to give it a try. This is great thread. At first look I though it was a bit thick, but I tied 10 loops today and this stuff is good! Stretches nicely, and while I did mess up tying a couple (my fault), none of them broke.

I had my wife look at it under different lighting conditions and angles. She never saw it. I can barely see it while working with it, I think only because I know where to look.

I would say I would buy it again, but a thousand fool spool makes about 1,000 loops. This is a lifetime supply for me! 😎

An almost infinite supply of thread. Great quality, great strength, great invisibility.
