The banger brush features a thermoplastic brush head that is soft on the glass while having high heat resistance to stand up to the high temperatures of a warm nail. In addition, the self-cleaning head wicks oil and wax from your banger and releases it into the unit's cleaning solution. These features help you clean your banger and pearls in under 5 seconds, saving you time and money by reducing the number of q-tips needed to clean your banger to perfection.
