1. Materials?a?aThe salt and pepper grinder is made of high quality clear glass (not cheap plastic or acrylic), stainless steel and ceramic grinding rotor. The non-corrosive ceramic pepper grinder does not produce unpleasant taste. The clear glass is visible and lets you know when it's time to refill. 2.Complete with Accessories?a?aOur salt and pepper set includes a stainless steel stand for your spice grinder to keep your kitchen clean and professional. With wear and tear in mind, we've added two spare ceramic grinding rotors to the package for easy replacement of your rotors after extended use. 3.Adjustable Coarseness?a?aSelect different grinding levels according to different flavors. You can easily rotate the knob on top of each pepper and salt grinder to adjust setting from coarse to fine (anticlockwise for coarse and clockwise for fine). 4.?a?aFits your hand with the perfect size of 5.5 inches tall and 2.6 inches wide. The wide glass body ensures that you can fill the spices very easily. The salt and pepper grinder has a large capacity of 180ml, which means you don't need to refill it as often. And you can easily see how much spice is left through the glass body.
