Crafted out of solid walnut and aircraft- grade aluminum, our ONGROK 3” Walnut Aluminum 2-Piece Grinder is perfect for any home setting. We use a neodymium magnet which keeps the lid securely in place, so it’s easy to open and access inside contents. Inside of the aesthetic finish, this grinder uses 48 diamond shaped teeth, to provide a medium-to-fine grind, every time.
