This is a Fukuro obi
with appealing Michinaga-dori ( shape of segments of Washi papers ) pattern, which is woven.
Gorgeous 'Kiku'(chrysanthemum), Matsu (pine tree) and waves are designed partly, and foil threads included in the pattern twinkle gently.
Textile is soft silk.
It has folding lines, and stains B next to Maegara, but if you start wrapping the obi from your right tummy to left(Rotate obi counterclockwise), stains side will not show.
Please see photos for details.
Overall, it is in very good condition and can continue to be worn!
