Size: M There are no noticeable stains, but this is a used item, so please purchase only if you understand. I strive to ensure smooth and courteous transactions. Please refrain from price negotiations if you are not serious about buying. Also, I will not offer significant discounts. I am also listing this item on other sites, so I may suddenly remove the listing, or it may be canceled depending on the timing. Thank you for your understanding. Thank you very much :)
