This dual wall thermal banger is an attachment that you connect with your bong to easily convert it into a Dab rig. It is sporting a twin wall design and that allows for the chamber to insulate itself and keep the heat for a longer period of time. This is great because it gives you the option to start at a lower temp so that you can keep all the taste in your terpenes. Another great thing that is included is the directional carb cap that helps you vape up every last bit of material that you put into the heating bowl.
