This is a vintage Maru obi
with bamboo and 'matsu'(pine tree) pattern, which is woven.
Textile is exquisite silk and has soft touch.
Its length is rather short. 388cm(12'8")
The Otaiko part is set upside down, and it's to be tied in 'hikinuki' style.
It has a horizontal stripe (Its width is about 2cm=0.7in.) around circle mark of the figure. Different color thread is woven only on the line.
Large stain will be prominent when tied.
However, folding line is slight and not disturbing.
There are other couple of flaws.
Please check detail photos.
This piece seems not to have enough strength to tie.
