Used once for a kindergarten overnight stay. I don't see any dirt or stains. It has only been washed once, but there is some fading in the navy blue parts due to washing, so I have marked it as "Slightly damaged or dirty." Please understand. The string in the first photo was just arranged in a heart shape for the photo; it's a normal string. Please understand the fading, etc., and purchase if you are not concerned about minor details.
