I'm selling this because I was concerned about my baby's plagiocephaly and bought it, but my child didn't like it and I didn't use it much. Although my baby didn't use it much, I kept it in the baby bed, so there is some pilling and fuzzing. There are no tears. I threw away the instruction manual, so everything in the photos is included. 【Materials】 Cotton, plastic beads 【Target Age/Weight】 0 days to 10 months (2kg to 9kg) Color: Mint Green For healthy spinal development, it's very important to maintain a rounded back with "marumaru nen-ne" (round sleeping). However, since a baby's head protrudes backward, if nothing is placed under the neck, the chin can be pulled back too far, making it difficult to breathe. Use the MyPillow Neo, a baby pillow that can be used from 0 days old and adjusted as your baby grows, to protect their comfortable sleep and healthy posture! I will send it in a waterproof cover. Thank you for looking.
