This kit features adjustable length and an undrilled Peppermill top. The quality ceramic grinding mechanism is adjustable directly for different coarseness. Grind peppercorns or any spice - it will never rust. The mechanism features a 10" shaft, which can be cut to make mills from 4" to 12" long overall (Use 9" extension #FEX9 for longer lengths). An internal spring catch inserts into the top to eliminate the need for an adjustment knob.
