Featuring a signature form by the internationally known glass blower and designer Micah Evans, the GRAV® Yoyo Carb Cap is perfect for pairing with a heady rig or daily driver. 

This directional airflow carb cap will bring out the best of your concentrates by improving the quality and control of your concentrate. By trapping and retaining heat, the user can maneuver the carb cap around to modify airflow, which improves convection at lower temperatures. This gives those smooth and flavorful, milky white draws.
