This 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. These terp pearls are meant to create additional surface area to thoroughly vaporize concentrates. The beads come in a reusable storage jar with a built-in carb cap base.
