This is a Fukuro obi
with graceful design of noshi, flowers and flying cranes pattern, which is woven.
Sparkling foil threads used in the pattern makes this obi suitable for a formal usage.
Textile is soft silk.
Both ends are closed, but there is no lining inside.
It has some stains on Otaiko pattern, but they may be disturbing when tied. (sorry no photos)
It has some other flaws, such as folding lines and smudges on both edges (fifth photo below the drawing image), as shown on photos.
Please see photos for details.
If you do not mind the small flaws mentioned, it can continue to be worn.
