Embroidered han-eri (collar). Although there is no material label, I believe it is silk based on the texture. It adds a touch of glamour to the neckline of furisode (long-sleeved kimono), homongi (formal visiting kimono), tsukesage (semi-formal kimono), iromuji (unpatterned kimono), etc. This is an unused item, but please consider it with the understanding that it has been stored. The color is not pure white, but a natural ivory. #ma embroidery han-eri
