OXO’s Sleek Adjustable Salt and Pepper Mill set has a top-grind design that offers mess-free storage- no more salt or pepper left on the counter or table. A wide opening on the bottom makes refilling the mills easy. The grind selector locks into 5 different positions from fine to coarse to suit your taste. Ceramic grinders won't corrode or absorb flavor or odors. The set comes filled with salt and peppercorns.
