Boro Farm Glass worked bubble caps are hand-blown from quality borosilicate glass. Boro Bubble caps increase airflow to maximize the vapor production of your quartz banger, making sure no dabs are wasted and all oil is vaporized. Bubble caps are effective and simple to use, just set the carb cap on top of your quartz banger or move it in any direction to push your wax or oil to the corners of the banger.
