The rest of my glasses (most) are Duralex as well. They're just very ... durable. I was kind of getting annoyed that the brand became so popular that I see them everywhere now (every other cafe serves water in them). I'm not French btw, my love for the glasses simply comes from seeing them outlast time and many pretty dramatic falls (a few times on hard ceramic tiles from a meter up and bouncing up almost as high again - leaving a few nearby mouths agape in the process). But reading that they're a worker owned cooperative makes me want to buy many more from them. That's what I want: Stuff that's build to last a long time by people who can live from their work. Who cares if they look dated? For something that's used daily being old is a testament to their quality. I use my IKEA-Duralex glasses almost daily. They look much cooler than any new shit with their battle-scars ight scratches :-D). IKEA is literally the opposite.
And for what it’s worth, if you don’t like the Picardie glasses, they have like a dozen other shapes that might feel “modern” enough.
