This is a vintage Maru obi
with flower pattern such as 'Kiku'(chrysanthemum), bamboo leaf and 'kiri'(paulownia) on diamond, which is woven.
With its chic color hue, it shows sedate atmosphere.
Textile is exquisite silk and has soft touch.
The fabric of the edges is getting weak by fray.
(not indicated on the sheet/ refer to the 6th flaws photo)
It has some other flaws such as tears on the edge (refer to the 2nd flaws photo) and a hole (refer to the 3rd flaws photo).
For the details, please refer to the photos and the sheet.
Unfortunately, it is no longer wearable.
The wonderful textile could be useful for your handicraft.
