User blog:TravelAddict1967/Cersei's wine glasses at King's Landing

I hope you will forgive my "dorky" request, but I'm trying to find out where the wine glasses are from that Cersei drinks from often and hopefully available to purchase. They appear to be hand-blown with a wide open base (almost as if you can flip upside down and use another way), and glass design on outside of the glasses too. I have searched online and Game of Thrones site, but coming up empty.

This is the best photo I could find of her drinking out of them so you can see what I'm referring to.

Thanks for any help you can provide! Love the show, have to read the books still.
