Used it for dried herbs from my garden.

This not only works as a weed grinder but it also works great on dried bay leaves which we grow in our yard. To of BB-8 is connected through a strong magnet once the herb is ground the screen catches the large stem that is left on after picking the leaf off of the plant. Smaller ground parts are caught on the bottom. I used it for my herbs but I will be giving this to my sil since he is a star wars fan.
