It��s the only party pack you��ll ever need. The extra-large growler features sTHEtanley��s tough construction and cold-trapping insulation with a heavy-duty steel-lined lid to keep your beer fresh and bubbly for 24 hours. The rugged handle lets you carry and pour one-handed, and the four stackable stainless steel tumblers are color-coded to avoid accidental swaps. Fill, pour, serve, cheers.
