CrushGrind mills are made from high-quality ceramic, hardwood, and stainless steel parts. Each mill comes with a 25-year guarantee on the ceramic parts within the mill. These mills stand at 8" tall. While the pepper mill can obviously grind peppercorns, you can use it to grind other spices like coriander, cardamom, or allspice. Each mill is filled with Tellicherry peppercorns or Meditteranean coarse sea salt before they are shipped.
