【Excellent Condition】Posture Correction Cushion - Seitai KA·RA·DA Factory Zazen

This is a posture correction cushion purchased from the chiropractic massage store KA·RA·DA Factory.
It has only been used for half a day, so I believe it is in relatively clean condition. Only the main unit is included.
