Use this replacement sponge with your glass rimmer / margarita salter to quickly rim your glasses! Glass rimmers are a handy bar tool that allow you to easily rim your drinks with brightly colored sugar or salt. To use, soak your sponge in citrus juice or liqueur. Press the rim of your glass into the damp sponge to moisten it, then press the rim into the sugar or salt compartment. Clean your sponge thoroughly at the end of the night and replace it often to maintain a sanitary drink station!
