This Kyocera Ceramic Coffee Grinder features a grinding mechanism that never alters the flavor of the beans, resulting in fresh, flavorful, and pure coffee every time. The grinding mechanism is made from an advanced ceramic, close in hardness to diamond, that will never rust, providing ultra long-life performance. The grind adjustment allows for fine to coarse grinds and the non-slip base ensures stability. The glass container is dishwasher safe. Great for Turkish coffee, salt, pepper, green tea & sesame seeds too.
