The inset design of the quartz nail keeps your concentrates and oils precisely where they should be; accessible and contained, ready to be torched. The difference is that with the inset design, there is nearly zero chance you wind up with dabs in the neck of the nail. Concentrates can be expensive so you should not waste any by losing it inside the curvature of the neck and joint. The barrier formed from the inner wall prevents this from happening. If you really want to protect your concentrates, combine a carb cap with the Quartz Thermal Banger Nail. There are options available when it comes to size, gender, and angle so this dab nail can fit any 14mm or 18mm dab rig. Have a 45° angled joint on your dab rig and are sick of your banger nails leaning awkwardly? Choose the 45° option and notice the longer, more straight neck. The joints come randomly in polished or frosted glass.
