These are simple free fleece-lined pants, an original brand of Akachan Honpo. The side pockets are fake, and there is only one on the back. They are made of a soft, stretchy material that doesn't restrict a baby's movements and are made of warm fabric. They have been used to some extent and have a vintage feel, but there are no noticeable stains or fraying, and I think they can still be worn. - Color: Pink - Size: 80 - Design: With pockets - Material: 96% cotton, 4% polyurethane Thank you for looking.
