To avoid being conspicuous, the makers of this herb and spice grinder/sifter have designed it to look like a grinning bronze skull wearing a crown.
It comes apart in the middle and the bottom half is meshed so it can sift out the best elements of your herbs and spices. Below and also able to screw-off is what I'm going to call the essence-capture chamber.Known as the King Skull Grinder for good reason, that being that it's a skull and wears a crown.
