"Beading enthusiasts everywhere love this beading thread, created by Japanese Master Beader Sonoko Nozue. Made in Japan of 100% Nylon, K.O. is a pre-waxed, colorfast, abrasion- and tangle-resistant thread, which can be knotted tightly and securely. It’s an excellent alternative for Nymo and is similar in diameter to a Nymo size B. It can be used with size 10 or 12 beading needles.
