I purchased this last year on a certain flea market app. I don't know the details. The following is the seller's description: ※ This is a Nero Ma-Shin Blue minor seal. ※ No comments, instant purchase OK. ※ Since this item has been in someone else's hands, there may be some dirt or scratches. ※ Please check the images carefully and only purchase if you are satisfied. ※ We do not recommend purchasing this item if you are looking for a perfect item. ※ We do not accept returns to prevent item substitution.
