To write up an eBay listing for stuff that you own and are looking to get rid of, or stuff that you sold for many years and are extremely knowledgeable about, than it is to list stuff that you know what it is, but nothing about the market for the item.
A friend has never sold anything on eBay. Purchased, yes, but not sold-so I am tasked with listing the things and well, the listings are not my usual descriptive sales spiel. I didn't realize how difficult it is to list stuff you're not personally invested in!
We'll see how this goes.
