Coffee and Spice Grinder Lid for Mason Jars

Cup, lid, and handle are made from high-quality stainless steel, while the ceramic grinder ensures a precise grind. The grinder allows you to change your grind size to your preference. Note that the top nut may be brass or stainless steel during a manufacturing transition to stainless steel. To clean: Simply grind a small amount of uncooked white rice to keep the grinder in top condition. To adjust the grind size: Remove the top nut, the handle, and the round piece under the handle. Screw the gear shaped piece up and down the threaded rod. You will see the 2 pieces of the ceramic grinder moving closer or farther apart. Clockwise for finer grind. Counterclockwise for coarser grind.
