Adding fresh-ground sea salt or pepper to food can be as effortless as a flip of the wrist. Invert these battery-operated mills over food, and their blades begin to whirl. Turn them upright, and the mechanisms shut off. Made by Trudeau, the innovative automatic design lets you grind salt or pepper with one hand - just turn the grinder over. Made of stainless steel with a satin finish. Corrosion-proof ceramic grinding mechanisms. An acrylic window displays the contents and fill level. Because the mechanism is on top, the grinding residue is neatly contained between uses. Each mill uses six AAA batteries (included).
