A carb cap is a must have dabbing accessory when using domeless nails. To use a carb cap you heat your nail like you normally would, drop your material in and then cover the carb cap over the domeless nail. These caps restrict airflow to your nail and increase flavor and efficiency. Carb caps allow you to do low temperature dabs for better flavor and to ensure you get the most out of your concentrates. Carb caps allow your nail to retain heat for a longer period of time. We offer a large variety of popular carb caps such as bubble, directional, spinning and even fun ones! We carry a carb cap to fit any type of dab nails.
