Keep grinding on with refill salt for your Kona Sea Salt Grinder. From the depths of 2200 feet below the ocean surface, Kona Sea Salt has a purity you can taste. 100% deep seawater is dried naturally under the Hawaiian sun producing an exquisite gourmet finishing salt. Kona Sea Salt Grinder Salt has slightly less moisture than our flake salt while retaining all the flavor! Like our flake salt, it contains less sodium than ordinary table salt.
