The Ooze Saturn Globe Grinder is a 50mm 4 piece grinder with a neodymium magnet and features razor sharp teeth. It is made from aircraft grade aluminum and has an anodized finish so it is scratch resistant. 

This design is different from a standard 4-piece grinder. The top chamber holds full, unground CBD and hemp nugs to be saved for later. Load one in between the teeth, and place your thumbs on the two thumbprints for extremely comfortable and ergonomic grinding. The grind will fall through to the bottom chamber, which also contains a pollen scraper.
