This is a simple Fukuro obi
with stone path and flower diamond on 'kikko ' (tortoise shell) patterns, which are woven on both edges.
This simple design will brighten up you on the scene for sure!
Foil threads woven on the background aee modestly shining.
Textile is exquisite silk and has textured touch.
There is not folding lines and it seems to be untied one.
It has molds on the wrong side overall. (*It is indicated as stain on the figure.)
Please check detail photos.
However, please enjoy its refined design!
