I have a brand new unopened BB-108-FX Hyperblade L Drago Destructor still in original packaging that I really want to sell. I want to start an auction and winner will buy from me on a selling app on mercari, auction ends tomorrow 12AM EST. Starting bid will be $50

You need to show a photograph of your item with a piece of paper with your username written on it, as proof that you own it.

i wouldve shown on mercari listing

Well it does not work like that here hah. Especially if you are going to have people bother to go through an auction for who knows how many days, they should at least see the product beforehand. Nobody's time should be wasted.
