This is the "Hitsuji no Iranai Makura" (Pillow You Don't Need a Sheep), which has been talked about on social media and in the media as being "like zero gravity." I am selling it because it didn't suit me. It uses a new material called "TPE (Thermoplastic Elastomer)" which has a rubber-like elasticity, and is characterized by a unique sleeping comfort that disperses pressure the moment you put your head on it. It is very breathable and can be used comfortably even on hot nights. 【Condition】 • Stains/Scratches: There are no noticeable scratches or tears on the main body. Since it is a washable material, I have carefully washed and dried it once before listing it. • Accessories: Only the "pillow body" shown in the image. A dedicated cover is not included, so please use your own pillowcase (standard size). ※Please understand that this is a used item before purchasing.
