Hitsuji no Iranai Makura (Pillow You Don't Need Sheep) ht-001 I used this for about a month after purchasing it. After that, I stored it away. The box has some damage, but the main body is relatively clean because I used it with the special cover and then a pillowcase on top. Please refer to the 3rd and 20th photos for the size. It can still be used for a long time. Thank you.
