The Terp Slurper Marble Set from White Rhino is a 3 piece set with different sized terp pearls. Made for use with a Terp Slurper style banger--a banger with a lower stem and tray--customers can use these terp beads to maximize the vapor they get from their concentrates. The small 14mm terp pill fits into the lower stem of a terp slurper banger to stir up any concentrates stuck in the chute, while the medium 11mm ball sits at the top of the lower stem to regulate airflow. The large 24mm marble functions as a carb cap, ensuring no vapor escapes from the top of the chamber.
