Extend the life of fresh herbs in your refrigerator with the Herb Keeper. Simply fill with water to the fill line, place herbs in the tray, and immerse the base, keeping leaves above the water line. (Make sure that the stems are immersed in the water so that they are hydrated.) When needed, suspend the tray on the supports to pick herbs. Standing 9-1/2" in height and 5" in diameter, the Herb Keeper fits conveniently in the door of most refrigerators.
