The Derwent copper mill set features 2 contemporary styled mills, presented in stainless steel, with a premium copper finish and clear acrylic body. The pepper mill has a carbon steel precision mechanism which cuts and strips peppercorns to promote the slow release of flavour, while the salt mill has a diamond ceramic grinding mechanism. Each mill has pre-selected settings to enable you to choose from fine to coarse grind for perfect and precise seasoning.
