This is a casual Tsumugi Nagoya obi
with trees on mountain pattern, which is roughly woven.
Textile is exquisite Tsumugi
silk and has nubby and soft touch with rusty atmosphere.
It is sewn as "matsuba-shitate" (open Nagoya obi
with tightly folded end of belt part).
Although not shown on the figure and the photo, it has tiny patinas overall. (They are not noticeable when tied.)
It has discoloration overall, especially both edges are rather prominent.
For the details, please refer to the photos and the sheet.
It is still in good condition.
Enjoy wearing the fashionable design.
