It's a bit puzzling why you cannot list Ray Ban products on eBay when in fact there are thousands of listing for Ray Ban.
Did you use the "RaybanÂ®" trademark in your listing (title/description)? according to eBay -
If you are selling a brand name product, you can probably show a picture of the product and refer to the company by name, but you cannot do so in such a way that it suggests that your auction is approved, sponsored or endorsed by the manufacturer.
I'm really curious what went on on your end, so do update us!
Hope this helps :)
