With a top opening stainless steel cover, the LOHAS Home Salt and Pepper mill set is both elegant and practical.As the grinder itself is on the top of the mill, it makes the salt and pepper go exactly where you want and will not create a mess on your table. The sealed lid also reduces moisture and other unwanted particles entering your salt & pepper mill.Each of our grinders in this salt and pepper grinder set features a ceramic burr grinder. Ceramic grinders are often considered superior to stainless steel ones as they are harder to wear out, and can work more effectively in moist conditions.
