A grinder is a great way to break up your tobacco or legal herb into same-sized pieces in order to allow it to burn evenly and consistently. The grinder also serves a second purpose, which is providing a screen which automatically sifts out the smallest sized particles from your product and collects them in the bottom chamber.
Grinders are made to last from a zinc alloy that is both durable and strong.
The bottom two chambers are connected by threaded joints, and the top chamber by a magnetic joint which allows for grinding of the tobacco or legal dry herb.
