I’d say that the most famous Duralex glasses in France are the ones used in most school cantinas for decades. Small, tough and with a small random number written at the bottom that was an excuse to play game with (smallest number on the table loses, etc.).
And that $30 price for the “Picardie” tumbler is astronomical! Duralex sells 6-pack of 12oz for 12,5€ on their own website and they are 5,99€ on Amazon.fr!
