So you're worried that someone will accuse you of selling a fake if you don't have any feedback? I really don't think you have much to worry about if your stuff is real... which I know it is.
What you need to do is take super good, detailed pictures. Do you have a macro setting on your digital camera? I use that all the time to take pictures of stuff I'm selling. Also... most to the auctions that get reported as having fake merchandise are reported by KKO. They are a great bunch and they know their stuff. So if they happened across your auctions, I'm sure that they wouldn't report you. All you need to do is sell a couple of nice bags to some people and get some positive feedback about your bags. So you chances of selling something will improve with each item you sell. I hope this helps some.
