The Cole & Mason 505 Salt & Pepper Mill Gift Set is built around our precision grinding mechanism. Both mills come partially filled upon arrival. The peppermill comes with whole black peppercorns from Vietnam. The salt shaker features coarse sea salt from Belgium. 505 Salt Mills feature a diamond cut ceramic mechanism that will smoothly produce perfect size grains every time. 505 Pepper Mills implement a hardened carbon steel mechanism that does not crush peppercorns, but strips them to release the maximum amount of flavor with each turn. Conveniently select between fine or coarse granules by simply adjusting the knob featured on top. Refilling is as easy as unscrewing the same knob and pulling the top open. Matching 505 Salt & Pepper Mills are made of high quality acrylic that will last for years to come.
