Black Leaf Science Master pre Cooler

This is a bullet-proof Black Leaf bong buddy that's guarenteed to keep your bong gunge at bay! There's a reservoir above the perc that catches any unburnt particles, stopping them from even getting to the bong. In the main chamber there's an 8 arm diffuser, which is what most perc bongs boast! This will split the smoke and cool it down to stop even the freshest toker free of a throat shred.

This guy is for the bigger bongs and bowls out there, 18.8 gauges all round! Oh, and it's 5mm glass so it's pretty durable. Does not include a bowl.
