The new Spice Grinders bring a functional item to life in your kitchen. They are ideal for grinding salt and pepper, but they can also grind most other herbs and spices. In addition, they have the added advantage of being fully adjustable from fine to coarse grinding depending on personal preference. The grinding mechanism is made from extremely durable ceramic, this material is as hard as steel but does not corrode like metal. The Spice Mills are easy to refill and wipe clean
