Using locking mechanisms and a magnetic top, the 4-Piece Medium Radial Teeth Aluminum Grinder is able to keep your herbs safe until you are ready to pour them out. The strategically placed anodized teeth shred your herbs, sending them once they are ground fine enough into the herb chamber. A mesh screen separates this section from the pollen catcher at the bottom. A scraper can be found here so you don't have to try to use your fingers for those tiny leftovers. The Sweet Tooth name is etched into the top. The 4-Piece Medium Radial Teeth Aluminum Grinder comes in your choice of striking color.
