This is a casual Tsumugi Nagoya obi
with mountain range pattern, which is roughly woven.
The vibrant 'Kumihimo'(braided cords) is woven in the background.
Textile is exquisite silk and has nubby and smooth touch.
It has whitish discoloration on upper otaiko(square bow), but it will be hidden when tied.
(refer to the 1st & 2nd flaws photo)
It also has relatively prominent folding lines.
For the details, please refer to the photos and the sheet.
It's still wearable enough in very good condition.
Please enjoy its elegant design for everyday fashion.
