Tobacco Grinder – 4 Part Super Heroes – Gunmetal with Crank 78mm is the perfect style for those who like things modern. This specific grinder has a crank on the lid that helps rotate the teeth in the grinder. With its special filtering chambers, you are guaranteed a roughly fine grind. The 4 piece grinder starts with a tough top magnetic layer, followed by the grinding chamber. As you twist it, razor-sharp teeth will grind the herb into fine little pieces that will fall through the 2nd layer onto the 3rd layer. Once they get there, they are fine and crisp enough to start your smoking session. Finer products keep falling until the base chamber, where the pollen screen allows only the smallest particles to pass through, catching that precious extra-potent fairy dust. This Tobacco Grinder – 4 Part Super Heroes – Gunmetal with Crank 78mm is perfect for those who prefer a finer grind, and really want a lot more ease and flow in the crushing process.
