Geo Pillow M Size Size: Approximately 230 x 330 x 60mm (Recommended for head circumference of 41cm or more) Purchased around September 2024 on Amazon. I am selling it because I didn't use it much as I often sleep on my stomach. There was no spit-up, and I think the condition is good. It has been washed at home. There is no box or instruction manual. I will compress it so that it can be shipped via Nekopos. Thank you.
