Thank you for viewing. This item was received from someone else and appears to have been used for handmade kumihimo (braided cords) as a hobby. It may be a bit more yellow than the images suggest (possibly silk thread). One end is frayed. I couldn't read what was written on the sticker on the other end (Kaiguchi?). There are no labels or markings. I am not able to determine the condition or quality of the item. Please feel free to ask any questions in the comments, and I will investigate as best I can. It is highly likely that this is silk thread from Domyō, but there is no guarantee, so please purchase with that understanding. I cannot make precise determinations about the specific specifications or materials. Please check the photos for the condition. Please forgive any oversights as this item has been stored at home.
