200 yen off for followers. It's cool! I'm sorry, but I can't tell what the material of the sleeves is because I'm not an expert. I couldn't find any tags either. Shoulder width: Approximately 55cm Body width: Approximately 50cm Length: Approximately 62cm Sleeve length: Approximately 63cm I don't see any noticeable scratches or stains, so I think it will continue to be useful. I am selling it because the size didn't fit me. Please understand that this is a used item before purchasing.
