The obiage (sash tie) can also be used as a han-eri (collar). Both items have only been used once. Please see the 3rd photo for an example of the obiage being worn, and the 4th photo for the han-eri. Regarding the obiage: I have too many turquoise obiage. Regarding the han-eri: It's a stiff lace type, which was too irritating for my sensitive skin. I'm selling these two items together at a great price.
