The set consists of six glasses that are 7-3/4 ounces in size.
It is the original french tumbler, produced by the company that first developed tempered glass.
Compared to regular glass, Duralex is 2-1/2 times more resistant to breaking and chipping, and can endure rapid changes in temperature from -4-degree F to 212-degree F.
Duralex glass is highly hygienic, as it is non-porous and does not absorb liquids, colors, or flavors. Additionally, it is free of lead, cadmium, and BPA.
These products can be safely used in the dishwasher, fridge, and microwave and will maintain their original appearance for many years.
