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 have been used. (It doesn't seem tangled, but I'm not sure. I haven't examined it closely because I'm afraid of tangling it with my rough hands.) Some parts have definitely been used. The weight includes the bag. There are no labels or markings. I do not know the condition or quality of the product. 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 with that understanding. I cannot make precise determinations of detailed specifications or materials. Please check the photos for the condition. Please forgive any oversights as this item has been stored at home.
