In a household of 3 clumsy girls (I can bank for the fact that clumsiness is indeed genetic), we need hardened utensils, that can survive a lot of rough and tumble. Thus, I am a big fan of Duralex, famous for making the same iconic hardened glasses for the last 60 years at least.
Have you ever been served a coffee in a little glass in a French café? Probably a Duralex Gigogne glass. Show any French person a Duralex Picardie glass and it will take them back to their school cantine days, where everyone got to drink out of Duralex glasses. I love their utilitarian chic and the fact that they are almost unbreakable (I say almost, as I will never forget my mother trying to demonstrate how unbreakable these glasses are by hurling one on the floor, where it smashed into a thousand pieces, much to her embarrasment!). They are perfect for families with young kids, especially if you are getting a bit tired of colourful plastic cups.
I picked my glasses up at Merci, but I also found them on this website which deliver internationally. Alternatively, you can find them in most French hardware shops. For our readers on the other side of the Atlantic there is a dedicated USA Duralex website!
