The RAW Life Grinder is made from 6061 aerospace-grade aluminum-magnesium alloy in an 18,000 PSI press to create one of the toughest and most durable grinders of all time. Inferior grinders just grind your herbs, but this piece of perfection also perfectly fluffs your material, so it is the perfect consistency to use with your RAW Rolling Papers or any other smoking apparatus. We also love how easy it is to clean this grinder, easily breaking apart into all its separate pieces, and that each chamber has a lip to prevent your material from making its way into the threads and getting them stuck. Still not convinced? RAW is so confident you'll love this grinder and that it will stand the test of time that they back it with a lifetime guarantee! If you ever have a problem, just head over to RAW's warranty claim form, and they'll have you back up and running in no time.
