This is a velour pajama from Inujirushi Honpo. [Reason for "Slightly Damaged or Dirty"] Upon checking the product before use, the buttons were generally sewn loosely, so I reattached most of them. The thread color differs on the reattached buttons. There are no particular stains or odors. I used it for about a month during the cold period after childbirth. The material is soft and warm, making it comfortable, and it made my postpartum life, which consisted mostly of pajamas, a little happier. Please check the Inujirushi Honpo website for product details.
