The RAW LIFE Grinder is modularly engineered to last a LIFEtime! Every component is easily cleanable and replaceable, even the screen. You can add or remove components onto your grinder and customize it exactly the way you like. Personally, I remove the screen and use it as a whole leaf grinder (grinding directly into the super large catch basin). Designed to not only shred your stuff, but to fluff as you grind to give you the perfect consistency materials to roll up in a RAW Paper.
