This is an opened vintage Nagoya obi
with a design of 'sasa'(bamboo grass) and kanoko dots on 'matsukawa-bishi'(pine bark diamond) and 'ume'(Japanese plum), which is dyed.
Textile is chirimen(crepe) silk and has soft but textured touch.
Maegara(front design) is only one side.
When you start wrapping the obi from your right tummy to left(Rotate obi counterclockwise), designed side of maegara will show.
Threads on the edges of otaiko and maegara(front patterned part) are missing by fray.(2nd flaw photo)
It is discolored noticeably overall.
Besides it has some other flaws such as a folding line and smudges along the line.
Please check photos for details.
Though it has some flaws by ages, please enjoy its full taste of vintage!
