Before buying online from various websites, a personal authenticity check is inevitable. I will gladly review the images you send me to evaluate a products authenticity.
If you already own the item, it is recommended to take as many high resolution images as possible, so that the authenticity check can be done faster and with more care.
I have helped many people authenticate items in the past and I do it mostly for fun. I am a LV and Hermes addict and counterfeit items are something I am completely against.
