Abstract
A grinder used to grind material, such as tobacco leaves and other dried fruit and herbs, having windows or plastic covered openings that provide visual access to the interior of the compartment in which the finely grinded material is collected. These windows or plastic covered openings allow the user to visually determine whether sufficient material has been grinded without the burdensome task of repeatedly opening and closing the compartment. Furthermore, the grinder of the present invention is designed to allow the windows or openings to be covered and sealed by a single clear plastic part that is injection molded directly onto the sidewalls of the grinder.
