The GRAV Glass Joint System is where simplicity meets the purity of glass for a clean, flavorful smoke every time. This three-piece setup ensures a seamless smoking experience. A silicone grommet tightly seals the borosilicate cartridge to the mouthpiece, keeping your flower in place. No more worrying about questionable paper or glue ingredients interfering with your pure cannabis taste. These glass joints are built to endure and are designed for lasting use. Plus, they're incredibly affordable, making replacements a breeze when accidents happen. Whether packing one joint for an afternoon hike or prepping all seven for a weekend getaway, these joints are your ideal travel companions. Each GRAV glass joint has a 0.5-gram capacity, allowing you to enjoy just the right amount of flower. When all seven joints are filled, they collectively hold approximately 1/8th of an ounce of your favorite herb. It's the perfect balance of convenience and versatility. With this complete system, filling all seven joints has never been easier. Our specially designed funnel and tamper, crafted from ABS food-grade plastic, make the process easy. Just align the funnel's holes with each joint, pour in your flower, gently press it down with the tamper, cap the end, and you're set for your next adventure.
