Duralex's Gigogne Tumblers named after an old French word meaning "nested" and as the name implies, these simple, understated glasses are meant to be stackable and easily stored. The Giogone Tumbler has been a standard for French mothers who covet glassware that is easily handled, shatterproof, and dishwasher safe.
