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 is a yellow-green silk thread. 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 do my best to investigate. It is highly likely that this is silk thread from Domyo, but there is no guarantee, so please purchase with that understanding. I am unable to make precise determinations regarding the detailed specifications or materials. Please check the photos for the condition. Please forgive any oversights as this item has been stored at home.
