The Boreal collection is crafted from beech wood sourced from French sustainably managed forests (with PEFC certification). Boreal mills are designer favorites, with a minimal and simple profile and thoughtful color palette that makes for easy combinations between pepper mill and salt mill sets. Boreal's lighter salt mill finishes and darker pepper mill tones allow for easy identification of whether you're picking up salt or pepper. In the center of the mills are Peugeot's lifetime-guaranteed steel mechanisms, which unleash pepper's full bouquet of aromas and deliver the desired sprinkling of salt, with long-lasting performance for fans of authentic flavors. - Mechanisms come with a lifetime warranty - Five-year warranty for the salt and pepper mills - Peppermill for grinding black, white, green, red, and pink peppercorns (up to 15% in a blend) as well as coriander seeds - Grind adjustment button: the tighter it is screwed, the finer the grind, and vice versa
