BEER BANDS are durable, reusable, stretchy molded rings sized to fit beer bottles, beer cans...and wrists! We"ve packed 12 bands into every clamshell - the perfect party-pack! There are 4 styles to choose from but Fred especially likes the Designated Driver style - it reminds everybody who"s safe to get behind the wheel and who"s not! So now that you"ll finally know whose beer you"re drinking you can pay full attention to remembering to drink responsibly.
