Thank you for viewing. This item was received from someone else and appears to have been used for handmade kumihimo (braided cords), a hobby. It may have been used. It doesn't seem to be tangled, but I'm not sure. I haven't examined it closely because I'm afraid of tangling it with my rough hands. The weight of 42.66g is without the bag. There are no labels or markings. I do not know the condition or quality of the item. Please feel free to ask questions in the comments, and I will investigate as much as possible. It is highly likely that this is silk thread from Domyo, but there is no guarantee, so please purchase with that understanding. I cannot make precise determinations of the detailed specifications or materials. Please check the photos for the condition. Please forgive any oversights as this item has been stored at home.
