This is a pillowcase specifically for the low (Version 2) "Suyayaka Pillow" from Zenkenkai (全健会) Chiropractic. It's almost the same shape as the original white cover that comes with the pillow. ● Due to being handmade, there may be slight imperfections or differences in color from the photos. Please refrain from purchasing if you are seeking perfection. ● Aotake pillow covers are also available separately. ● When purchasing multiple items, I intend to deduct the shipping cost savings. There may be multiple items in stock. Please feel free to inquire. Please refrain from requesting price reductions.
