Terp Pearls are great for adding extra heat retention to your banger - which allows you to vaporize your concentrate at a much lower temperature while still finishing off the whole dab.
Paired with a directional cap they are very effective at moving your concentrate around your banger - enabling a much more efficient vaporization experience.
