Thank you for viewing. I purchased this item on Amazon around May 2025 and used it only once. However, I was hospitalized shortly after, and after being discharged, I started using a reclining bed at home, so I no longer need this pillow and am putting it up for sale. I purchased it for a high price of 19,800 yen, but unlike the cheap triangular pillows that often have a plastic smell or lack cushioning, this one, designed by a Korean doctor, has a moderate firmness, and I believe the materials are of good quality. I used a thin futon over it even during the single use, so I think it's in a clean condition, but please understand that it has been stored at home. - Brand: Dr. Shin - Color: Gray - Type: Positional Pillow - Accessories: Storage bag, Manual #Dr.Shin #DrShin #TriangularPillow #AcidReflux
