Enhance your dabbing experience with the GRAV Hourglass Banger Set! Constructed from premium quartz material, this banger has a beveled top edge compatible with the marble style carb cap. The banger's thick bottom ensures lasting heat retention and the fully welded, seamless joint promotes longevity no matter how often you dab. This bucket's inward curvature creates a distinct hourglass silhouette designed to function well for those who prefer cold start dabs, preventing concentrate from slurping up the sides before fully melted. Angled port holes are on the side walls of the bucket to create a spinning airflow; this vortex twirls the two quartz terp pearls around within the bucket to stir melted concentrate for maximum vaporization. Each banger has a 14mm male joint connection size and a 90 degree joint angle.
