Introducing the Homegrown® Standard Quick Lock Grinder by Cali Crusher, a groundbreaking American-made herb grinder with innovative features. This designer grinder boasts our unique 4-Way Quick Lock System, eliminating the common problems of cross-threading and jamming that come with traditional threaded grinders. Upgrade your grinder effortlessly with a removable 210 count micron screen, using a Philips head wrench. Made of premium 6061 aerospace aluminum and protected with type II anodizing, Cali Crusher Homegrowns are built to last. Equipped with strong neodymium earth magnets, they ensure a tight hold and are scratch-resistant thanks to bead blasting. Our ultrasonic cleanse guarantees a clean, metal shavings-free product, while the CNC fluid application makes it medical grade. The drop holes are larger for a free flow grind, and offers a smooth twisting action. The rounded bottom chamber makes collecting hash a breeze, and our patented radial blades cut one way and fluff the other for maximum shred. Teeth are covered under a lifetime warranty, and the package comes with a guitar pick scraper for convenience. Grooved edges offer easy grip, and the product is proudly made in San Diego, California, USA. Measuring at a diameter of 2.22" and a height of 2.03", this grinder is the perfect size for all your herb grinding needs.
