This is a hanhaba obi (half-width obi). Due to long-term storage, there are storage stains on the entire back side. They do not appear on the front side. The material is silk, and it makes a rustling sound similar to a Hakata hanhaba obi when touched, but there is no certification tag. Therefore, I will sell it to someone who understands this. Length: Approximately 315 cm Width: Approximately 14.8 cm Regarding the color, since I am a amateur photographer, there may be slight differences in the shade of color between the photos and the actual color. Please consider this before purchasing. If you have any questions, please comment before purchasing. When shipping, it will be folded small and shipped with simple packaging.
