Duralex Gigogne Mug

The Gigogne mug is made in France from Duralex's tempered glass, making this mug the closest thing to unbreakable you'll ever find. Duralex glass can withstand the thermal shock of sudden temperature changes from -4 degrees F to 266 degrees F. Plus, it's 2.5 times more break and chip resistant than ordinary glass, and naturally, it's safe in the freezer, microwave and dishwasher. The Gigogne mug has a capacity of 7.5 ozs.
