Nishikiito is the Cosmo brand metallic thread for hand embroidery. This thread is crafted with the same technique to produce gold thread used in traditional Japanese clothing in the former capital of Japan, Kyoto. Not recommended for machine use.
Nishiki style is the type often used for Obi belt of Japanese traditional clothing, Kimono. This thread has subtle metallic colors and is resistant to friction, good for not only stitching but also making tatting lace and tassels.
