Hyperflite's Jawz disc is the toughest and best-flying puncture-resistant disc ever made. The Jawz disc stands up to gnashing canine teeth better than any other competition disc. All Jawz discs feature Hyperflite's patent pending X-Flash™ Anti-Glare Technology. Although the Jawz disc is remarkably tough in normal canine play, it is not intended to be used as a chew toy. Jawz discs do not float in water.
