First and foremost, there are 4 chambers in the grinder. The topmost chamber grinds your herbs, while the next chamber catches the ground herbs. From the herb chamber, tiny particles of herb fall into the pollen chamber. The very top of the grinder is clear, so you can see your herbs being ground. The middle portion of the grinder is also clear, so you can see where your ground herbs are stored. You can use this middle portion as a storage unit by inserting a barrier. As for the material of the grinder, it is almost completely made of aluminum. Grinders are a necessity for the average smoker, and Kannastor grinders are engineered to take that into account.
