She has some small scabs/marks on either side of the underside of her jaw.  This was caused by rubbing between the lip of the tub and the rack while poking and prodding for an escape route.  I've seen this in ball pythons many times in the past.  It never seems to get any worse and may actually get better if she's kept in a tub where she's not trying to escape.  I've priced her much lower than if she was perfect. If you are seriously interested in her, please let me know and I'll send you pics.
