The luminescent metallic embroidery threads by KingStar have a polyester core and are wrapped in rice paper with a metallic finish. The high- quality thread doesn’t “kink” up as it unwinds from the spool and runs smoothly through the thread pre-tensioners, resulting fewer thread breaks and higher quality embroidery.
KingStar thread is certified according to Oeko-Tex Standard 100, Class 2
