Review on Green Fox Run Marble Mortar & Pestle by Rebecca Johnson

I love the fact that this very neat mortar and pestle can grind substances into a fine powder. I can control the level by the amount of "elbow grease" I apply. This is important to me as I currently use it to grind catnip for my pets. The fineness of powdered catnip means you won't choke on the hard sticks and stalks. My cats seem to like the catnip even more, it's so finely ground now.
