The cold start banger is the newest quartz nail that dabbers are raving about. Doing a proper cold start will take some experimenting, but basically this banger will allow you to drop your concentrates into the dish and torch it from the outside afterwards. This process is a lot quicker, where you only need to torch with the tip of the flame for about 5-10 seconds. With a traditional banger, you would torch for 30 seconds or so, then let it cool down before taking a low-temp the dab. This just speeds up the process with less wasted product. The matching carb cap and rounded bottom keep the oil moving towards the middle for a nice efficient dab.  Specifications Joint Size: 14mm Male & Female Joint Angle: 90 Degrees Includes: Cold Start Banger & Matching Carb Cap
