The mills come unfilled and the sets are presented in premium gift boxes. Clean with a microfiber cloth to keep it looking its best. The grinding mechanisms (sharp anti-corrosion ceramic for salt, design registered Precision+ carbon steel for pepper) are supported by a lifetime guarantee. This allows you to season with confidence, knowing you will achieve a high-quality output and consistent milling time after time.  Salt mills are fitted with an ultra-sharp ceramic mechanism that does not corrode with time. Pepper mills are fitted with a design registered Precision+ carbon steel mechanism, that strips peppercorns instead of crushing them, ensuring maximum flavor release from every turn. To clean, wipe the mill with a damp cloth and use a clean cloth to dry. We recommend you do not use any cleaning products as this can affect the aesthetic finish of the product. Do not immerse in water or place in a dishwasher. All Cole & Mason salt and pepper mills are covered by a lifetime mechanism guarantee. In the unlikely event you are experiencing any issues with the mechanism in your mill, please contact the Cole & Mason customer service team and they will be happy to assist you. Mills come unfilled, individual mills with swing tags, set packed in a gift box. Made of Beech Wood Measures approx. 8.5" Imported.
