This is a Tsumugi Nagoya obi
with "Karabana"(imaginary Chinese flower) on diamond motif, which is embroidered.
It has fine drawn works (one of the techniques of removing thread partly to make a ground textile seen through) ans Sagara embroidery technique.
Textile is rustic and soft Tsumugi
silk with knobs of yarns.
Although it's not mentioned on the sheet and photo,
there is a small hole(0.07"/0.2cm) which will be hidden when you tie it.
The stain(A) on upper 'otaiko'(square bow) will be hidden when you tie it.
There are some other flaws such as folding lines(refer to the 3rd flaws photo).
For the details, please refer to the photos and figure.
Enjoy wearing the fashionable design.
