This set of salt and pepper mills comes from the Oslo series by Cole Mason. These high-quality reels last a long time and have a sleek and timeless design. This makes them very stylish on the counter or kitchen table. The mills have an adjustable precision grinding mechanism, so you can adjust the perfect size of the grains for each dish. The salt mill has a mechanism of diamond-ground ceramic, the pepper mill of hardened carbon steel. This mechanism preserves the natural oils of pepper, ensuring a high-quality taste experience. The mills are pre-filled with coarse sea salt from Belgium and black peppercorns from Vietnam. When this is finished, the mills can easily be refilled by unscrewing the reservoir.
