Justace "Aurora" Metallic Thread - Size A

Compared to nylon threads, Japan's Just Ace polyester threads are less likely to deteriorate due to fading due to ultraviolet rays and reduced thread strength, have less fluff on the yarn, and can be dyed more stably than nylon threads, enabling a stable supply of "color". It is a parallel winding that is all colors and does not have a thread habit. Unlike metallic threads, "aurora threads" change color depending on how light hits and the viewing angle. In addition, due to the penetration of the coating agent, the color may show through or the finish will be different from the original color.
