Pillow with a breathable design ・10-year durability (won't flatten) ・Material Type: Shigoku (Standard Model) ・Retail Price: ¥15,800 I bought this new last May and used it for about a month, but it didn't quite suit me, so I stored it in the closet. I used it with a standard pillowcase over the dedicated pillow cover. I have disposed of the pillow cover and box, so I will pack it with the utmost care for shipping. Please understand that this is a used item before purchasing. ※I am a non-smoker and do not own any pets.
