Kannastor’s 6.4-centimetre four-piece grinder is made from durable aluminum and fit with a clear jar body so you can see how much you’ve ground up. It 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 grind-er comes with a limited lifetime warranty, a guitar pick scraper and a carrying bag. All sales are final.
