Terp pearls and marbles increase the efficiency of your banger. The marble cap sits perfectly on beveled edge bangers while the valve topper sits comfortably over the valve and the pearls in the vacuum tube.  Whilst drawing through your rig, the pearls work to constantly agitate and stir your concentrate whilst also functioning as a heat sink to ensure that it's evenly heated.  The marbles act together as a one-way seal to ensure not a wisp of delicious terp-laden vapor will escape.
