There is discoloration on the collar lining. I believe it's wool or a wool blend. Length: 148cm, Sleeve length from center back: 65cm, Sleeve length: 43cm. It will be folded to fit and shipped via Yu-Packet Post, so I cannot combine two items. They will be shipped individually. If you purchase 5 or 6 items, I will consider shipping via Takkyubin (home delivery service), but the shipping cost will increase significantly, so the discount will be minimal... I cannot reply to combined purchase requests due to the system, so please contact me via comments. Please note that items may be compressed for shipping. *Please read the profile and understand before purchasing.
