This is a tsuzure Fukuro obi
with elegant clouds pattern, which is woven.
Gold foil threads included in fabric and the pattern twinkle gently.
Textile is silk, and it has crispness to the touch.
Both ends are closed, but there is no lining inside.
It has rather prominent folding lines, and they are lightly discolored along.
Discoloration on Maegara (A) is not disturbing.
It has some other flaws as shown on photos.
Please see photos for details.
If you do not mind the small flaws mentioned, it can continue to be worn.
