This 14mm flat-top banger is made of 100% quartz. Each 14mm bucket is 3x thicker than your standard banger, retains heat for longer, and spreads heat more evenly due to the seamless design. The banger has been paired with the GRAV® Yoyo Carb Cap to improve the quality of your dab hits by maintaining temperature and modifying the airflow to improve convection. Each banger is also paired with three quartz inserts. These inserts help keep the banger clean and are excellent for low-temperature dabs.
