Get the most out of every hit with this banger loop. These uniquely designed glass pieces are made to ensure the maximum amount of flavor while also allowing for large vape clouds. The loop around in this piece ensures heat retention and recycles any of your unused oils so you get the most out of every session. First heat the quartz diamond knot insert and drop it into the banger. Then place your concentrates on top and cover with the glass carb. Your concentrates will fill the loop and pour back out onto the diamond knot to be vaped again making sure you never leave any precious oil behind. This particular piece is a 14mm Female joint and will fit a 14mm Male joint.
