Although I'm not the venerable and respected Eddie51, I do sell a lot of Vintage Ray Ban Aviator sunglasses in Europe (and elsewhere) on E-bay.
When you first select 'Sell' the opening page asks you to describe your item. You can then proceed to "Creat Your Listing". On that page, scroll down to "Give Buyers Shipping Details". Within that block you'll see "Exclude Shipping Locations", followed by "Creat an Exclusion List". When you click that link the next page is where you include or exclude certain locations... check there to see what you have.
I have full confidence EDDIE51 would have given you the same advice except he sleeps in a lot. (I'm in the U.S. by the way. My ebay ID is Vmc120k... cryptic, no?)
