Keep your spices fresh and store them in these Wooden Salt and Pepper Mills! The set comes with two pieces of kitchen spice grinders! Since they are wooden, they don’t corrode or rust so the spices stay fresh. You can also adjust them depending on how fine you want to grind the spices. There are five levels you can adjust to from coarse to fine. For fine grinding, turn the nut clockwise and for coarse grinding, go counter-clockwise.
