Roro is sold, thank you :)
Cute little Roro comes with both faceplates and both have the most adorable Face-up by Kesha. She is normal skin (I didn't notice any yellowing, so if she has some, it would probably be very even) and I am not the first owner of this item.
Overall she's in very good condition. The only thing that comes to mind is, that she probably could use some restringing in her legs? At least I've always been of the impression that her right leg is a little bit more floppy than her left leg - but that might also be just me not getting along with tiny dolls like these.
