Muji flannel pajamas, navy check pattern, size 100-110. 100% cotton. The buttons are large and each one is a different color, so children can dress themselves easily. There's a button on the side of the jacket to secure the pants, preventing the stomach from being exposed. The sleeves and hems have elastic, so they're warm and can be worn even if they're a little big. These were worn by a child, but the fabric is sturdy, so I think they can still be worn. Please understand that these are used items, stored and washed at home, and purchase accordingly. I will not offer a discount.
