It's like my dilema. I bought a framboise vernis koala wallet from a lady ( for 180...good deal! ). When I bought her I didn't realize until I got home that she was just a weeeee dirty ( probably a little colour transfer ) but other than that she was perfect!
It did bother me a little bit at first, but its been almost 2 days now and I'm learning to love the little flaw that she has. It just means she's more special than any other vernis framboise wallet out there.
I think if you wanted it for so long a couple little marks shouldn't matter, because that iswhat makes you love your wallet even more later on. But, if it really super bothers you to the point where you can't stand iut, take it back : D
