The latest carb cap to join the collection features a unique design that utilizes carved channels to control airflow, and (of course) make those terp pearls spin. Made of high-quality quartz, the Disc Cap gets its name from its base shape. But, unlike the other quartz caps in our inventory, there’s no air hole on this handle. Instead, air makes its way through the tiny swirled channels carved in the cap’s thick and disc-shaped base.
