Dab Tool l Carb Cap

A carb cap is a small, dome-shaped device that is placed over the nail of a dab rig. It is designed to cover the nail while you take a hit of your dab, trapping the vapor and allowing you to inhale it at a lower temperature. The cap typically has a small hole in the top that you can cover and uncover with your finger to control the airflow.
