The Impervious Crystal Cut 11 oz. Margarita Glass.

This elegant tableware is made of the same durable polycarbonate used in fighter jet canopies, so it will not crack or shatter, yet it is molded in the shape of fine cut crystal for use at formal holiday gatherings without the risk of breakage. Microwave and dishwasher safe, the tableware will not crack or craze from multiple washings, and the insulating properties of polycarbonate help keep beverages at a consistent temperature for longer. Set of six 11 oz. Margarita Glasses.
