At 2.2" this grinder is perfectly average. What it lacks in size, it makes up for in personality and sharp teeth. 4 pieces create a super functional little grinder with a sifting bottom for your herb to fall through and catch in the middle compartment. The screened bottom allows that fine pollen and kief to fall through into a collection tray for a rainy day. Comes with a pollen pick and a magnetic closure for the perfect grind every time.
