【NITORI】Neck-Supporting Neck Fit Pillow (High Breathability/N-Breath Plus Air P2428) Thank you for viewing. I purchased this at a Nitori store around summer and used it twice with a towel. However, it didn't suit me, so I've been storing it. I'm selling it as part of my year-end decluttering. I threw away the box, so I will put it in a plastic bag and ship it in another box. - Product Name: Neck-Supporting Neck Fit Pillow (Breathable Neck Fit Pillow (N-Breath Plus Air P2428)) High-Breathable Neck Fit Double Pillow - Size: 35 x 50cm - Features: High breathability, washable as a whole - Color: White/Gray - Adjustment Function: Height adjustable (medium/low) The height adjustment sheet is inside.
