I've quite a few small, somewhat eclectic items which have been listed for a while (euphemism for "years"). Recently I sold a 60s eyeshadow which was one of those items. It sold to the Stage Manager at a London theatre, so I guess it will be a prop. 2 days after I posted it, I got a message asking for it .... from another potential buyer.
I have a limit to the amount of space I allow these items to take up, but they often do sell... eeeeventually!
