This is a vintage Maru obi
with design of thin wavy lines and Matsu (pine tree), which is woven.
Gold foil threads included in fabric and the pattern twinkle gently.
Textile is silk, and it has slightly textured touch.
It is slightly discolored throughout, and it has patinas.
Corners of Tare and Tesaki ends are fraye.
Both edges are smudged in full length.
It has some other flaws, such as stains and prominent a folding line, as shown on photos.
Please see photos for details.
Due to its old age, it has some flaws, but it still is a very charming vintage obi.
