This is a pillowcase from the Fabe Medical pillow sold by Tsuhan Seikatsu. It is included when purchased, and is a 100% cotton pillowcase. * 4 unused items. * Pillowcase only. Pillow not included. * These pillowcases were included when purchased in February and May 2025. The bag that the pillowcase from the February purchase came in was discarded, so it is in a different bag. * Although it has been stored at home for a short period, please refrain from purchasing if you are sensitive to this. If you would like to purchase a set of two, please comment. Thank you for looking.
