Glycerin Glass Bubble Carb Cap

Get the most out of your dabs with a carb cap that steps it up a notch! The classic bubble cap design has had a unique change-up with the addition of glycerin. This allows you to freeze the carb cap to add a light amount of cooling to dabs as it travels up and down the tube, or leave it as-is and the glycerin is a cool-looking design element in itself. Carb caps are the best way to create a seal on your nail to control airflow, and the rounded design allows you to easily swivel it around any flat or diagonal dab nail.
