New, unsewn Nishijin-ori rolled bag obi. Mother-of-pearl is used in a part of the design. Mother-of-pearl inlay is a technique of cutting, polishing, and layering shells such as turban shells and abalone into various thicknesses, then fitting them into the design for decoration. I think this is a very fashionable obi. This is a rolled bag obi, so the lining and obi core are not included. Please understand this before purchasing.
