Rechargeable Electric Pepper Grinder Salt And Pepper Mills Type-C Charging Spice Grinder With LED Light Adjustable Coarseness. Get fresh ground spices with just one touch: Tap once to turn it on, during the grinding process, you can easily operate with one hand without pressing and holding the switch. Unlike a gravity-operated grinder that returns the broken pepper to the container every time, this grinder doesn't need to be flipped. The crushed pepper will stay at the bottom and will be ground first the next time you start, so you always get fresh spices instead of peppers that lose their flavor in the container.
