This is a vintage summer ro Maru obi
with elegant 'karabana'(imaginary flower in China) pattern, which is woven.
Textile is transparent silk and has soft touch.
Its length is rather short. 404cm=159in ('rokutsu'(approx 60% of the both sides are patterned))
It has flaws such as prominent folding lines and a hole on blank part of bodice.
Please check detail photos.
*It has a rather strong mold smell.
It has flaws like this, but there is not very serious damage for wearing.
