4 Piece Aluminum Herb Grinder with Interchangeable Mesh Screen By Interplanetary Development (2.5 Inch Super Weapon II, Pink) EASY LOADING: Weve removed a few teeth from both the bottom and top of the grinder. This creates an area where you can easily load your herbs. Its a small, unconventional idea, that makes grinding so much easier. INTERCHANGEABLE MAGNETIC SCREENS: Its now easier than ever to replace your grinders screen with our new magnetic design! We believe you should replace your screen, not your grinder. CUSTOM METAL PICK: Weve designed a new metal pick that perfectly contours to the curve on the bottom collection chamber. UPGRADED THREADING: Our new large threads unscrew in one full revolution. Relieving the frustration of having to make multiple revolutions, while also being 4 times as secure as quarter-turn threading. LIFETIME WARRANTY: The Super Weapon II now comes with a lifetime warranty! Free. Making it the last grinder youll ever need to buy.
