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. Includes patterns. I am not able to assess 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 the silk thread is from Domyo, but there is no guarantee, so please purchase with that understanding. I am unable to make precise determinations regarding detailed specifications or materials. Please check the photos for the condition. Please be aware that this item has been stored at home, so there may be some oversights.
