This is a no frills, 4pc metal grinder that crumbles and breaks your herb to perfection. A magnetic lid encloses razor sharp teeth that pulverize your flower to excellent consistency. The storage area has a mesh sifting screen that suspends the flower above the kief collector. Inside this grinder you'll find a pollen scraper to help scoop your kief. The signature Green Monkey logo sits nicely on the top of this herb grinder. The rainbow effect on this tool is a subtle yet cool touch, making this the perfect high quality grinder for any customer.
