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 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 of the detailed specifications or materials. Please check the photos for the condition. Please be aware that this item is stored at home, so there may be some oversights.
