I like to buy milk in the half gallon size, fresher is better and I don’t drink enough so a gallon will spoil before I can use it all up. I repurpose the container as a very handy trim paint holder. Use a sharp blade and cut out the jug as shown it will really save those aching fingers from trying to hold on to an awkward can. Be safe when cutting, never cut towards yourself, always away from your body!
