Toker Premium 5-Pc Titanium Herb Grinder 2-Pack

Especially good for things like oregano, basil, rosemary, and thyme.

Weird brand name, Toker. Vaguely rings a bell.

Will this grind black pepper corns?

No. They don’t really grind very finely. They’re made specifically to grind up “herb” in a gentle manner and the screen and lower chamber is to filter and capture the trichomes (“kief”). This is for marihooch.
