The Krave 2.5 Inch 4 Piece Grinder is one of the most innovative grinders out there. This one of a kind grinder connects each compartment using strong earth magnets, instead of the classic screw-ons. Although each piece is held together with a set of four magnets, the magnets are strong enough to prevent the pieces from accidentally coming apart. Included with the purchase of each Krave Grinder, you will receive a pollen scraper to easily pick up the finely ground pollen from the pollen chamber. The unique diamond-like teeth equipped in this grinder provides the perfect grind for any of your favorite dry herbs.
