This is a Nagoya obi
with exquisite Sayagata, 'kikko'(tortoise shell), and 'seigaiha' (wave) on 'zigami'(paper cut of shape of fan or umbrella etc.) pattern, which is woven.
Gold and silver foil threads included in the pattern are making this obi twinkle.
Textile is soft silk.
Along the wrinkles below the Otaiko pattern is slightly discolored. (sorry no photos)
It has some other flaws, such as folding lines and smudge, as shown on photos.
Please see photos for details.
Although it has some flaws as mentioned, it still is a very charming item to wear!
