Easy Pen Grinder is a fully automatic grinder that works on a chargeable Li-Ion battery. There is no easier way to grind. Traditional grinders are poorly designed, with no simple way of filling papers or bowls without making a mess. The Easy Grinder, however, is here to end that struggle. It works electronically or manually, complete with LED lights, a magnetic seal and a manual crank. Just fill up to 2.5 mg and dispense how much ground up material you desire. The longer you press the button, the finer your herbs become. Large bulky grinders have become a thing of the past. New Easy Grinder is here to make your life easy.
