This is a casual Tsumugi Nagoya obi
with colorful geometric pattern which is roughly woven on a deep colored background.
Textile is rustic Tsumugi
silk and has nubby touch.
Other than rather prominent folding lines, the pattern part has patinas though they are slight.
There are some other flaws such as whitish stains as well.
Please check photos and a figure for details.
It will be still tie-able if you don't mind minor flaws.
Enjoy casual fashion with this piece!
