These are B-grade items exclusively for repeat followers. Individual sales or pattern exchanges are not possible. B-grade items may have misprints, loose threads, or be smaller than regular items, and have a "B" stamp on the tag. You have not been informed of the specific defects when purchasing, so the B-grade areas are unknown. Therefore, I cannot answer questions about them. B-grade sets will be listed on the weekend of the Super Mercari Market. They will be deleted in one week.
