We tested a number of grinders before choosing this robust, portable grinder made from aircraft-quality aluminum. It’s lightweight, durable, and engineered for performance. Our 4-Piece MS Grinder uses razor-sharp, diamond-shaped teeth to finely shred your dry herb to the perfect consistency for your MagicStone. With a precision-balanced head and powerful neodymium magnet, it makes easy work of grinding sticky flower with every turning motion. The bottom tier is a fine pollen catcher and includes a cleaning brush and an integrated scraper for your leftover kief.
