This is the cheaper alternative for the Pollen Herb Grinder.
With it's razor sharp teeth, machined out of aircraft grade aluminium, these grinders can handle pretty much any smoking mix. The great thing about it though is that each time you use it a deposit of pollen will be stored in a chamber at the bottom of the grinder. This grinder is excellent at catching the crystals that would normally be lost when you skin up. Once you have collected enough pollen then you may be interested in the pollen press which compresses all the pollen into one small block. An excellent grinder for a good price.
