Copper Salt MillThe Copper Salt Mill has a strong food safe plastic mechanism (40% glass) 38mm diameter and stainless steel shaft to prevent corrosion. Equipped with 3DCut system, designed to really grind the salt and not just smash it, maximizing its flavor and aroma. Common salt mills only smash the salt which severely limits the flavor release. Each mill provides plenty of room for you to fill it with your favorite kind of salt. Grind directly over the food.
