Olde Thompson Olde Thompson pepper & salt mill. Height: 6.5cm, Diameter: Approximately 5cm. It's a small, manual mill. I used it to grind rock salt. The grind is medium (depending on the size of the salt, it could be ground finer). This is a spare I bought and kept at home, unused. Please understand this before purchasing. Set of 2, salt and pepper, or white pepper and black pepper, etc. How about it?
