Superior Materials - The Ultimate Herb Grinder

Our Quality Guarantee
Our products are meticulously tested to ensure you receive the best quality possible. We stand behind every product we sell with our industry-leading Masterdam 100% Satisfaction Guarantee.
The Sharpest Teeth on Any Grinder
Often imitated, never duplicated, our exclusive "Lion's Tooth" shape curved diamond teeth cut and fluff the herb into small pieces perfect for rolling. Our grinders increase the surface area of your herb so you get a more even grind and in turn have less wasted product. It's also a lot easier on your fingers.
The Power of Attraction
Our grinders have a Powerful Neodymium magnetic lid and Non-Stick Nylon O-Ring, which keeps it freely rotating for an easy grind while keeping all parts together, so you don't lose any of your precious cargo, even when on the move.
