Kannastor’s 6.4-centimetre four-piece grinder is made from durable aluminum and features a magnetic air-tight lid to secure dried flower in place, and its drop-through hole design keeps larger pieces from falling through. It has a secure grip with grooved external edges for easy use, and a monofilament screen to separate the pollen. Available in multiple colours, this grinder comes with a limited lifetime warranty, a guitar pick scraper and a carrying bag. All sales are final.
