This is a vintage Maru obi
with wave and large 'Kiku'(chrysanthemum) pattern, which is woven.
Its bold large pattern is eye-catching.
Textile is silk and jinken (rayon) blend and has relativelycrisp touch.
It has frays on both corners.
It has smudges throughout the edges.
It also has relatively prominent discoloration and patinas on the tare end.
It seems like the original owner of this obi enjoyed many fancy bow.
So that there are relatively prominent folding lines through out.
It has some other flaws such as tiny frays and snags.
However, please enjoy its retro vintage design!
