The mill is made from solid Acacia wood fully FSC certified, finished with 20 coats of high gloss lacquer hand polished between each coat. Using a ceramic mechanism, the mill requires a clockwise motion to activate. An Addison Ross exclusive design, the white lacquered bobbin-shaped mill comes with both an S and a P stainless steel screw knob so you can decide for yourself whether you want this to be a Salt Grinder or a Pepper Grinder.
