Our handheld metal herb grinders are crafted out of solid, aircraft grade aluminium, and come apart into four pieces. Inside of the aesthetic finish, our grinder uses 33 triangular shaped teeth to provide a perfect medium-to-fine grind, every time. The chamber has a removable micron mesh screen for easy cleaning, and the neodymium magnet keeps the lid securely in place and maintains freshness. Each ONGROK EZ Open Grinder contains a guitar pick style kief scoop. We know you'll love our grinders!
