2 in 1 Salt and Pepper Grinder: The double pepper grinder has a unique adjustable ceramic rotor, which is durable and can grind salt/pepper/spices quickly at the same time. Healthy and easy to use: our grinder salt shaker is BPA free and made of stainless steel. End caps can prevent salt or pepper powder from escaping. It can grind natural and unprocessed dried herbs.Flexible Coarse-to-Fine Adjustment: Adjust the coarseness and fineness by simply turning the knob on the ends of the spice grinder. You can also disassemble the salt mill parts for cleaning.Keep the taste fresh: The salt and pepper mill can be completely sealed when not in use. This will prevent moisture and dust from keeping the pepper and salt dry, and also won't affect the taste. No need for multiple grinders: the pepper grinder bottle body is made of transparent ABS material, the spices are clearly identifiable, and you can enjoy the fun of grilling without buying multiple grinders.
