This salt mill has a traditional design with elegant curves that make it easy to handle. Made from high-quality, renewable wood, it has an internal nylon mechanism to crush salt crystals for enhanced flavor. Fill the grinder with salt and set the grind coarseness to desired setting by turning the adjustable top nut. The top crown allows you to lock the grind setting for consistent grinding every time. The internal pieces can be popped out for quick and simple cleaning and refilling. There is a lifetime grinding mechanism warranty.
