The banger is heated with a torch, and concentrates (like wax or oil) are placed in the bottom dish. The unique design with slanted air slits allows the included inner cone insert to spin rapidly when inhaling through the dab rig. The purpose: This spinning action, along with the included carb cap, ensures that the concentrate is evenly dispersed across the heated surface area, allowing for efficient, low-temperature vaporization and maximum flavor with minimal waste. The piece shown has a distinctive "lighthouse" or "charmer" shape for the main chamber and a matching pink-accented carb cap.
