This set does not require batteries and is made with a ceramic grinding mechanism for fine or coarse grinding based on your preference.
Just push the button. It is thumb-operated which makes it easy to use it with a single hand.
These beautifully finished grinders look great on tables or near the stovetop and work great with black peppercorns, sea salt, Himalayan salt, spices, and gourmet table seasoning. So what are you waiting for?
