Duralex Unie Tumbler

The bare-bones French tumbler that refuses to break.

Duralex has been tempering glass in France since 1945, and the Unie is its no-frills everyday glass: clean lines, comfortable weight, and tempered construction that is two and a half times stronger than ordinary glass. It shrugs off thermal shock from freezer to microwave, and on the rare day it does break, it crumbles into small pieces instead of dangerous shards. It stacks to save space, too.
