The White Rhino Terp Pearls are designed to improve the vaporization of your concentrates. Each pearl measures 6mm in diameter which is an ideal mid-range size, allowing you to use 1 or 2 pearls with most bangers, depending on your preference. Simply place into your quartz banger's bucket before heating it up and use a directional airflow or vortex style carb cap to spin the pearls around inside as you inhale; these awesome accessories increase the heated surface area within and help break up concentrates. Available as a 5-piece set.
