Kalorik Gravity Salt and Pepper Grinders automatically start milling when tilted down, and stop once turned back up. This gives you more control over how you season your food than normal shakers or grinders. Adjust the grind level from coarse for steaks and chops to fine for sauces, popcorn, and pastas. Rust resistant, high quality ceramic grinders have durable stainless steel housings so you'll have these for a very long time. Required 4 AAA batteries (not included) Stainless steel. 7¼"H x 2½" diameter.
