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. I don't think it's been used. (It doesn't seem to be tangled.) There are no labels or markings. I don't know the condition or quality of the item. If you inquire in the comments, I will investigate as much as possible. It is highly likely that this is silk thread from Domyo, but there is no certainty, so please purchase it with that understanding. I cannot make precise judgments about the detailed specifications or materials. Please check the photos for the condition. Please forgive any oversights as this item has been stored at home.
