I purchased this assuming it was an 8-sun Nagoya obi, but it doesn't have any stitching at the hand width, and the entire width is the same. There is also no core. I apologize, as I am not very knowledgeable about this. The design is very lovely, but I am selling it because I haven't had a chance to wear it. The price has been reduced due to overall fading. Material: Silk Length: Approximately 346cm Width: Approximately 29.6cm
