100% quartz drop-in was explicitly designed to fit our oil coil banger. The small drop in securely fits inside a 14mm banger and is intended to be removed with our heat resistant tweezers. The quartz drop-in is 2mm thick, so it won't easily crack or break if dropped.
The drop-ins are intended to keep your banger perfectly clean and allow for the best tasting hit while not wasting any material! Load the drop-in with your favorite concentrate, use the heat resistant tweezers to drop it in the banger and place your carb cap over the banger until it's ready to rip!
