Nishikawa AIR 3D Pillow LOW Type 61X34X11cm Retail Price: ¥18,700 *Pillow body only. The three height adjustment sheets (see image 4) have been discarded and are not included. I used it for about two months, but the height didn't suit me, so I'm selling it. I used it with another pillow cover and a towel wrapped around it, so there are no noticeable stains. Since it is not new, please purchase it if you understand this.
