Purchased on Rakuten in August 2025. Used a few times, but it didn't suit my child, so I'm selling it. When in use, I wrapped a towel or swaddling blanket around it to prevent direct contact with the skin, so there are no stains like spit-up on the cover. The pillow itself has some slight yellowing in places. It's not very noticeable visually. *Please refer to photo 4. Please understand that this is a used item that has been stored at home and used by a child. Please refrain from purchasing if you are sensitive to such things.
