This is an Oshima Tsumugi Nagoya obi
with a design of vibrant 'kumihimo'(tasseled cord), which is woven with fine cross Kasuri.
Textile is Tsumugi
silk and has soft and light touch.
It is sewn by Mitsukoshi one of the famous Japanese department store.
The flaw indicated as fray is actually slight discoloration, and it is not so disturbing.
As the 1st flaw photo shown, a liner flaw can be seen on the left side of otaiko.

*It has a bit of mold smell.
If these flaws do not bother you, it could be still worn.
