I own a LV Monogram Papillon 30. It was purchased in april 2004, not really used over 2dozen times. there is however a small watermark on the bottom of the bag. I'm considering selling it, but don't know how much I should realistically expect to get for it. I have the original receipt and it's been kept in a dustbag. The small pouch it came with is nowhere to be found so i'd be selling just the pap by itself. any thoughts?
