To ensure you get every last bit of concentrate from your dab nail, use the Directional Airflow Carb Cap. Able to twist while on your banger nail, this carb cap eliminates those pesky leftover puddles. A bent arm at the bottom of the carb cap can reach those corners resulting in full vapor hits. The Directional Airflow Carb Cap comes in your choice of color so you can match it with your dab rig.
