This is a brilliant vintage Maru obi
with dynamic young pine on wave pattern, which is woven.
The vibrant pattern emerges out against the gold threads woven background.
Textile is jinken(rayon) and has relatively crisp touch.
Not shown on the sheet and the photos, it has discoloration and patinas overall.
It seems like the original owner of this obi enjoyed many fancy bow.
So that there are folding lines and wrinkles through out.
There are some other flaws.
For the details, please refer to the photos and the sheet.
Although there are such flaws, please enjoy its design which only vintage items have.
