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. It's slightly more orange than H145. The red thread photographed at the same time is shown together for color comparison. Some black is reflected in the packaging, but it's on the bag. 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 Doumyou silk thread, but there is no certainty, so please purchase with that understanding. I cannot make precise judgments 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.
