MENU Bottle Grinders have a rounded base that fits perfectly into the hands, and have a rubber surface that’s easy to grip and to clean. The grinders have a powerful ceramic grinder, and they are very easy to operate. You simply open them, fill them with delicious ingredients and close them again. Simple as that. The unique, inverted design ensures that salt, pepper, pumpkin seeds, dried blueberries, walnuts – or whatever you fill them with - only sprinkle out when you grind, leaving no trace on the table or in the kitchen.
