A sleek one handed operation at a touch of a button, grinds salt and pepper effortlessly. Ideal for quick use when cooking or on the table to impress guests. The Richmond Electronic mills feature a hardened carbon steel mechanism for pepper and diamond sharp ceramic mechanism for salt and come with a lifetime guarantee. The Cole & Mason Precision mechanism does not crush peppercorns but strips them to release the maximum amount of flavour with each turn.We recommend using high quality peppercorns and coarse rock salt in all our mills.
