This is a Sumikko Gurashi child's sleep sack. It measures 50cm in height and 40cm in width when laid flat. There is no size indication, but it's probably around 100-110cm. A child who is 100cm tall wore it and the hem came to about their knees. It has been used for about two seasons and has some pilling, but I think it can still be used. Anonymous delivery. Immediate purchase OK.
