GravLabs Micro Hole Diffuser Perc Action Video

FunkyPiece carries the full line up of GravLabs concentrate rigs and water pipes. In this short clip we show you the very efficient perc action of the micro hole diffuser found in a variety of GravLabs pieces. The diffuser disc has micro holes that allow air to pass through as you draw on the pipe. The tiny holes filter and aerate your smoke for thick, dense rips each and every time.
