(4 PAK) 17 oz. Cobalt Blue Cooler - Made Almost Unbreakable by HercuGlass Feature

17 oz. Cobalt Blue Cooler
Strengthened by the Hercuglass Process, the same process used to make ultra-high strength Fighter Aircraft windshields, iPHONE glass covers and the EpiPen Cartridges.
Set of 4 Glasses - all HercuGlass treated
Great for Ice Tea, mixed drinks, soda, etc.

A beautiful, dark cobalt blue color in a glass that is ultra-break resistant due to the HercuGlass treatment - essentially the same process used to strengthen Fighter Aircraft Windshields and the iPhone cover glass. No glass is unbreakable, but these are the strongest drinking glasses you can buy.
