The Jawz flying 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 and weighs in at a beefy 130 grams. If Fido's plastic addiction is robbing you of your hard-earned dollars, the Jawz disc is for you. Although the Jawz disc is remarkably tough in normal canine play, it is not intended to be used as a chew toy. Measures 8-3/4" in diameter.
