This is a very handy and sturdy grinder. It's able to handle large amounts of flower, and it is built with a 3 level design for maximum production. The first level is dedicated entirely to the function of grinding down yourdry herb to the perfect crumble size. Level 2 is solely for catching your previously ground dry herb. The last level catches and stores any excess pollen that falls off your dry herb. There is also the nifty little window in the 2nd level so you can see how much you have inside, and can use this grinder as storage for later use.
