This is a Fukuro obi
with epic scenery pattern, which is woven elaborately.
Foil threads included in fabric and the pattern twinkle gently and makes this obi suitable for a formal usage.
Textile is soft silk.
Stain on one side of Maegara will not show if you start wrapping the obi from your left tummy to right(Rotate obi clockwise).
It has rather prominent folding lines and they are smudged along.
It has some other flaws as shown on photos.
Please see photos for details.
Overall, it is in very good condition and can continue to be worn!
