"2009's Best New Gift Idea"Set of 4: Jumbo-17 oz. Stemless Martini Glasses: The highest strength Martini glasses you can buy. The HercuGlass Process increases the strength of glassware by up to 300% (See the Santanoni Unbreakable Glass videos on Youtube) Some of our products survive drops from 10 feet onto a hard tile floor. While thin-walled Martini glasses may not survive such abuse, they are the STRONGEST in the world, and will survive mishandling that would easily break normal glass. They're a little more expensive, but in the long run you will save money and avoid possible injury. See "other Hercuglass products" for Margarita and Brandy Glasses.
