Kannastor's series of GR8TR grinders are some of the best on the market. The company is so confident in their product that it comes with a lifetime warranty.
Thoughtfully designed with modular components so you can take pieces out or add more. Switch between a fine grind for vapes or a standard medium grind for smoking. All the pieces are threaded so you can simply unscrew any piece that you don't want to use.
