This is a rich purple Fukuro obi
with two Chinese characters woven among the orange 'karakusa' (arabesque).
One of the characters is 'kotobuki' (longevity) woven with golden metallic coated threads, and I'm sorry but I don't know what the other one woven with Urushi
coated threads is...
Textile is silk, and it's very soft.
It seems difficult to wear this obi since the both side edges are torn about the otaiko (square bow) area.
There are other flaws such as prominent folding line and orangish stains.
For the details, please refer to the photos and the sheet.
