The Human Grade 2.5" Metallic Curved Grinder is a 2.5" (63mm) 4-piece metallic herb grinder with a curved, hourglass-shaped body that settles naturally into your palm. A glossy metallic finish covers each piece. Choose green, black, red, teal, purple or gold.
A Curved Metallic Herb Grinder Built for Grip
The body narrows at the middle and flares at the lid and base, so your fingers have a natural place to sit while you twist. That shape gives you more control than a straight-sided grinder, and the metallic finish gives it a polished look on the shelf.
How a 4-Piece Grinder Works
The top chamber holds the teeth that shred your herb. Ground material drops through holes into the middle chamber, where a fine mesh pollen screen lets only the smallest particles pass. Those collect in the bottom chamber, giving you a separate stash of fine pollen. The included scraper helps you gather it.
Cleaning Your Grinder
Tap out loose material after each use. When resin builds up, separate the pieces and soak the metal chambers in isopropyl alcohol, then brush the teeth and screen with a soft brush and let everything dry fully before reassembling. Freezing the grinder for a few minutes first makes sticky residue easier to knock loose.
