Two distinctly barrel-like blocks stacked atop one another, although these barrels are squatter than the typical vessel for alcohol. Both barrels sit above cylindrical pedestals The grinder rotation point is just above the bottom barrel. All four pegs are removable. The top two are for loading salt, the bottom two for loading pepper. There are six salt holes on the top surface of the mill.
