This is a fukuro obi with charming stylized pine bough pattern, which is woven partially with golden metallic coated threads.
This piece is made by Kawashima Weaving co, one of the most famous obi weavers in Nishijin Kyoto.
Pine motifs have pretty kiku (chrysanthemums) or auspicious takara assortments in themselves.
Textile is soft silk.

As the photos and the sheet show, it has a folding line.
Also, there is a faint patina on white near the tesaki end, though it's not in any photo.
However, they're not so outstanding as to make it impossible to wear this obi.
As a whole, it's in very good condition.
