I've used these versatile, virtually unbreakable glasses, a standby of Parisian bistros and cafes, since I was a kid. My sisters and I would drink milk from them; now, I reach for one when I'm pouring wine. Produced in France since 1929 by Duralex, the company that patented the process for tempering glass, Picardie tumblers are made of heat- and shatter-resistant glass, with an iconic fluted shape and a reassuring heft. After years of use, my set has remained miraculously scratch-free—it's a design that endures in more ways than one.
