I'm selling these because my child isn't interested in them. They're almost untouched, so I think they're in good condition. Some of them were opened for the first time to take photos of the last page (I heard the "peel" sound). "Sora" and "Iro" have some slight creasing on the covers, but the insides are in good condition. I haven't had them for a year yet, so there's no sun damage.
