This is a black fukuro obi with unique castle and 'kicho'( partition used by noble people in ancient days) pattern, which is woven.
Textile is silk, and it's soft.

The gold threads become uneven at places and gold part looks to have very small dots, and some parts looks like silver threads by fray (A) .
It has some other flaws as photos show.
However, the flaws are slight or small and not disturbing. As a whole it is in very good condition and it can be tied!

*Approx background color - Black
Softness ( Exceptionally Soft, □ Soft, Medium, Comparatively Stiff, Stiff )
