Weekday Collar

Mark the day a jar was opened

Snap the split ring round the neck of a jar of pesto, sauce or baby food the day you open it, turned so that day sits over the label. Days later anyone opening the fridge can read when it was opened, with no pen, no sticky label and no sniff test. Rinse and reuse it on the next jar.
