Bangers are good. Bangers with carb caps are better. But bangers with carp caps and terp pearls are best. This set is made for the dabbing enthusiast, combining a 25mm flat top quartz banger with a perfectly fitting cyclone carb cap and two glow-in-the-dark terp pearls. As you inhale through your rig, this uniquely designed carb cap will spin the terp pearls inside the banger pushing around your concentrates which increases surface area and heat retention. Basically, you get more bang for your buck. This function ensures none of your concentrates are wasted and everything is vaporized for maximum vapor production. The deep, recessed bowl shape is designed for heat retention, durability and efficiency. This design can be used with or without a carb cap and is still excellent at minimizing waste. These bangers are made with 4mm thick 100% quartz (not glass) for the tastiest hits. The 90-degree angle of these bangers makes them better suited for straight-up ground joints, or direct inject from the top, and compatible with female joints. To keep them clean, wipe with cotton swabs after every use. Available in 10mm, 14mm, and 19mm.
