Crafted out of solid, aircraft-grade aluminum, our ONGROK 2-Piece Grinder is almost indestructible. 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 28 diamond shaped teeth, to provide a medium-to-fine grind, every time.
