A unique spice grinder with a modern look that adds style to any table. By tightening or loosening the knob on the lid, you can adjust the thickness of the crushed spices. The spring-loaded mechanism does not compress the pepper as it grinds, but releases strips of ground pepper with maximum flavor with each turn. We recommend using quality spices in all grinders.supplied filledheight: 115 mmmaterial : acrylic
