Use the Washi Tape to Keep Track of Your Wine
Charming wine charms and all, but they only work with stemmed glasses. To keep track of your wine (or whiskey or beer) no matter what glass it is in, consider using a washi tape.
Washi tape, which is essentially a beautiful masking tape, adheres well to glass and comes in a wide variety of colors and patterns. Just write your name (or the names of your guests) on it and stick it on your drink to prevent drinks from being stolen and kuti being spread.
