The Copco Grinder Set is an essential set prefilled with sea salt and peppercorns and ready to flavor food; smooth finishes add a touch of style to your kitchen. The ceramic grinding mechanisms prevent corrosion and easily distribute seasoning. With an adjustable twist, the knob allows you to easily select how coarse or fine the grind is. Simply unscrew the tops, fill the large reservoirs, and replace the tops; glass reservoirs show when contents are running low. Sturdy constructions stand up to daily use
