This is a beautiful han-eri (collar) featuring roses and butterflies by Tamao Shigemune. It is made of polyester. I purchased this several years ago and have kept it stored at home, unused. My interests have changed, and I no longer have the opportunity to use it, so I am offering it to someone who will. It has not been opened, so I will send it as is. There is no visible aging or deterioration on the exterior, but please check the photos.
