CannaCrush’s four-piece 2.5″ grinder features 50 specially designed aluminum diamond-cut teeth and 30 grinding holes (made from aircraft-grade anodized aluminum on CNC machines) that are scratch resistant, which prevents flaking or pealing. Its knurled grip makes grinding easier, and the lid stays in place with a neodymium magnet that also keeps the odour locked inside and maintains freshness. The chamber contains an advanced micron mesh screen to filter the kief. Every CannaCrush premium grinder is equipped with a kief scraper, and a lifetime warranty. This grinder is available in black or grey.
