Although there are almost 10k of models in our database, there will be time that something you want to buy and sell is not in our model database. Choose "Others", then key in the brand, category and model yourself.
You don't need to create a new listing on the same item. Just go to My Selling list, click "Edit", change the status to "Currently Using" and save. Edit it again and change the status back to "For Sale", and then save it.
