A perfect gift for coffee lovers, this Kilner set includes an adjustable stainless-steel grinder that fits neatly atop a glass canning jar. Use the coffee mill’s crank handle to grind beans with a coarse, medium or fine consistency directly into the glass storage jar. An airtight lid is also included to preserve your fresh-ground coffee for later. Kilner canning jars have been celebrated as “the original and best” for over 175 years.
