This is a Tsumugi Nagoya obi
with wall painting like abstract pattern, which is woven.
The black stripe pattern has modern atmosphere.
Textile is Tsumugi
silk and has soft but nubby touch with rustic atmosphere.
There are prominent spots of molds on the wrong side of maegara(front patterned part).(indicated as stain)(3rd flaw photo)
However, when you start wrapping the obi from your right tummy to left(Rotate obi counterclockwise), they will be hidden.
Patinas and stains can be seen on the white base, and they are small but bothering a little.
Besides it has folding lines so please check photos for details.
If these flaws do not bother you, it could be still worn.
Please enjoy its fashionable piece as a daily wear!
