m. jacob & sons&rsquo 64oz. pet growler in light amber eliminates glass breakage, provides easy handling and pouring, and offers much lighter beer carrier. the pet growler also features a modified grip, and the amber color protects the beer from direct light penetration. the growler can also be taken to places where glass is not allowed, including beaches, parks, lawn concerts, and other outdoor venues. source httpwww.packworld.compackagetypecontainersmjacobsonsplasticbeergrowler
