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, providing a screen which automatically sifts out the smallest sized particles from your product and collects them in the final chamber.
The Thunderbolt grinder is built from zinc alloy for long lasting quality.
The bottom 3 chambers are connected by threaded joints, and the top chamber connected by a magnetic joint which allows for effortless grinding.
