Purchased in the spring of 2025. I've used it a few times, but it doesn't suit me, so I'm selling it. I also purchased a dedicated pillow cover (pillowcase, dark gray, second photo), and I used it with the cover on. (Therefore, I think the condition is relatively good) I will send the cover as a set to those who need it. *I've added a picture of the sponge in the third photo. I think it's in beautiful condition, with no deformation or discoloration. *I've added a picture of the bag in the fourth photo. Please purchase only if you understand that this is a used item. If you have any questions, please comment. #Nishikawa #AIR
