Petit Bateau cotton long-sleeved pajamas - Material: Cotton - Sleeve Length: Long sleeve Thank you for viewing. I purchased these online in the spring, but they were too small, so I am selling them because my child has outgrown them. There is a stain on the knee area, possibly from a pencil. As shown in the photos, the fabric around the knees is stretched. These are used items, so please consider this if you are not concerned about minor details.
