There are stains on the silk lining. I don't see any damage or stains on the outer fabric, but the material is unknown. It's not synthetic fiber or wool... Length: 144cm, Sleeve length: 61.5cm, Sleeve length: 52.5cm. It will be folded to fit and shipped via Yu-Packet Post, so it's not possible to combine two items. They will be shipped individually. If you purchase 5 or 6 items, we will consider shipping via Takkyubin (home delivery service), but the shipping cost will increase significantly, so the discount will be small... Due to the system, we cannot respond to combined purchase requests, so please contact us via comments. Please note that items may be compressed for shipping. *Please read the profile and understand before purchasing.
