Holzmuster-Grinder 2teiler, 50mm 12er-Pack

It sounds like you mean a "wood pattern grinder," which is a type of herb grinder typically used for grinding tobacco or herbs. The diameter of the grinder is listed as 50mm, which is a common size for compact grinders, and this particular listing or pack contains 12 pieces.

Here are some important points that might interest you:

• Material: Probably wood, as "wood pattern" suggests, although the inner molars may be metal for durability.
  
• Größe: 50 mm Durchmesser, was mittelgroß und tragbar ist.
• Menge: Eine Packung mit 12 Stück, die wahrscheinlich für den Einzelhandel oder Großabnehmer bestimmt ist.
