Well in that case I would mention it in the feedback - or just contact her saying 'these are well worn and stained, how about a partial refund' etc.
Ebay is very much 'buyer beware'. Always assume the worst and ask questions - if someone doesn't describe the item's condition properly then steer clear unless you don't mind taking a risk.
It took me YEARS to get the hang of this so it's not just you, but basically you have to be really cynical or you'll end up with a lot of tat and feeling like a mug.
Some descriptions are obviously really honest and genuine - the more writing the better, don't imagine a minimal sentence is going to turn into a magical bargain - it probably won't! 
So avoid those with poor photos and poor descriptions. Look for good feedback, look at the care taken with the listing, things they've mentioned to be honest (someone who actually says 'I like to mention everything just to make sure' is usually a good bet) and a cheerful tone in the writing.
And if in doubt do ask, because if you do end up disputing a purchase as 'not as described', ebay look at all the ebay messages you've sent each other - I had a buggy, the description was vague, so I asked what the condition was and they basically lied in their answer - 'YEAH ITS GREAT COND NO DAMAGE AT ALL' so I got it as it was sooo cheap. It turned up filthy and stinking of smoke with loads of damage - should have been binned. Really extreme!
I complained, they got abusive straight away, and said 'ha ha you should of asked' or something so I put in a dispute and ebay looked at their messages and knew they had lied.
they were so pissed off, they thought they had got away with it.
I cleaned it up and sold it for a few quid, they didn't want it so I got nearly all the money back from them too and made a profit.
Good luck - but always tread very carefully and don't buy something that's not described properly. x
