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. Perhaps it's for Tennoji braids? I'm not sure. I don't know the condition or quality of the item. If you have any questions, please ask in the comments, and I will investigate as much as possible. It's likely to be Doumyou silk thread, but I can't be certain, so please purchase with that understanding. I cannot make precise determinations about the detailed specifications or materials. Please check the photos for the condition. Please forgive any oversights as this item has been stored at home.
