Canna Crusher’s four-piece 2.5″ grinder features 40 specially designed aluminum diamond-cut teeth and 25 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 Canna Crusher premium grinder is equipped with a kief scraper, a travel pouch and a lifetime warranty. It’s available in black or grey.
