Six inches tall and quite slim, the Pump and Grind features a patented viewing window for distinguishing the salt mill from its matching pepper mill counterpart, and for viewing the level of salt crystals in order to prevent a shortage at a crucial moment. Vic Firth salt mills are fitted with nylon mechanisms, while those on the pepper mills are stainless-steel. The compact size of the mill enables easy kitchen storage or travel. Vic Firth backs the long-lasting mill with a lifetime guarantee.
