This is a tasteful Sioze Fukuro obi
by Kouhakushi Kumagai.
It has a design of 'aoi'(hollyhock) leaf, which is dyed on black background.
'Kinkoma'(golden outlining embroidery work) is added on the design partly.
Textile is shioze silk, and it has soft and comfortable smooth touch which is the feature of shioze silk.
It has a stamp of the designer's signature upper tare.
The stain on otaiko is slight.
It has slight folding lines.
Please check detail photos.
Although not shown on the figure, it is discolored slightly overall and has a whitish stain on blank part of maegara(front patterned part).
If these flaws do not bother you, it could be still worn.
Please enjoy its elegant fashion!
