4-Piece Grinders with Kief Catcher

A 4-piece grinder adds a fine screen and a bottom chamber under the grinding teeth, so the pollen that falls off your herb collects on its own instead of coating the inside of a 2-piece. Over a month that chamber adds up to a meaningful bonus.

The OG is our 63mm aluminium 4-piece with a 60-micron screen, magnetic lid and a guitar-pick scraper, in seven colours. The MightyROO Fifth Edition is the same layout machined from 304 stainless steel at 435 grams, with a travel case, brush and glass filter tip in the box. Two OGs for less is the Mates Pack. If you would rather nothing gets sifted out, look at our 3-piece threadless grinders.
