RO Oak Salt Grinder or Pepper Mill beautifully designed and German engineered are practical and distinguished. Each grinder/mill can be used for either salt or pepper, and the grain size can be adjusted. The units are oiled oak and the grinding device is ceramic. Grinds sprinkle from the mill from the top, avoiding the messiness of salt and pepper grains on your table or counter. Designed by German Theresa Rand in her Copenhagen studio.
