This domeless quartz banger nail is a unique concentrate accessory that provides several benefits over a standard quartz nail. The innovative banger design is available in your choice of clear joint sizes (10mm, 14mm, or 18mm) and fits easily over either joint gender of your oil rig. It has a bent glass tube that moves the heat of your torch away from your vapor rig to prevent heat stress and premature cracking on the joint. The nail utilizes an open dish where you place your legal oils and concentrates. The functional design of this banger quartz nail provides spacing from the dab rig extending the life of your rig by preventing breaking that can occur when you heat directly on the joint. This domeless banger nail is made of high quality quartz and is a great add-on to your concentrate rig. The joint comes randomly in either frosted or polished.
