This is a Shioze Nagoya obi
with vegetable pattern such as Chinese cabbage, eggplant, bamboo shoot and cucumber, which is dyed with Katazome(stencil-dyed) technique.
Textile is shioze silk, and it has soft and comfortable smooth touch which is the feature of shioze silk.
The flaw indicated as stain is actually dyestuff.(2nd flaw photo)
Although not shown on the figure, the dyestuff can be seen on the tare end, too.
The dyestuffs are small but prominent so they are bothering.
It is discolored slightly overall.
There are some other flaws so please check photos for details.
Though it has some flaws, we hope you enjoy its stylish fashion as a daily wear!
