I think eBay reckons that with 24 good clear photographs and a minute long video any item that could be tricky to see can be shown effectively on eBay. We can also fill in all the Item Specifics and even add our own Item Specifics to capture qualities of an item not captured in the more standard ones. It's a ton of work but might be worth it sometimes. Maybe. Possibly. Theoretically.  I have  uploaded videos to show musical boxes working and that helped sell them.
