Beautifully crafted granite top mills add elegance and style to any tabletop. Colour coded tops for salt and pepper. The ceramic mechanism is harder than steel, odourless, rust and corrosion proof with a 10-year warranty. Multi-purpose mill grinds pepper, salt, dry herbs and dry spices. Grind is adjusted by turning the top nut: turn it clockwise (tighten) for a finer grind; counter-clockwise (loosen) for a coarser grind.
