Used by Prime Minister Takaichi! Nitori Side Sleeping Pillow. Used for six months. As you can see in the photos, both ends are yellowed. It can still be used if you replace the cover. Please consider if you don't mind this. I'm generally a clean person and wash the pillowcase twice a week, and I sun-dry the pillow on sunny days. Ideal for those with stiff shoulders and those who often sleep on their side. Nitori Side Sleeping Pillow Prime Minister Takaichi Sanae Takaichi
