So I have about nine million gatcha items that I simply want to sell on the market place...My question is how? Do I need a magic box since the items are no copy? How exactly do I get the items to the market place from the magic box? AND.... If I am selling more than one of the same item I have read that you need to place the item in seperate magic boxs but then how can I link them so that I do have them removed and labeled spam? If there are tutorials on how to resell gatcha items and I have missed please link me them.
