GioPillow Premium Greige Sand M Size Retail Price: 8480 yen This is a pillow to prevent flat head syndrome in babies. Purchased from the official store in April 2025. I felt it was effective with the S size, so I bought the M size as well, but it seems the height didn't suit my baby, and they didn't like it, so I only used it for a few days. Home-cleaned. Due to the nature of the product, there are some areas where fiber debris has gotten in. I removed as much as possible, but please refrain from purchasing if you are looking for perfection. The original outer box can be included for an additional 500 yen. The shipping label will be attached to the outer box. If you would like the box, please let me know in the comments before purchasing. If there are no comments, the item will be shipped compressed without the box, so please be aware of this.
