Designed with sharp, diametrically-cut teeth that consistently grind herbs to a perfect texture, this multi-piece unit often includes a threadless quick-lock or magnetic lid system for smooth operation. The large size (~3.22″ diameter) offers ample room for grinding and storing material, and many versions feature extra functionality like a rolling paper holder, built-in ashtray, stainless steel pollen screen, and pollen catcher for convenience and enhanced utility. Manufactured in the USA with a sleek finish and ergonomic grip, it’s ideal for both everyday and heavy use.
