Black Leaf Recycle-Precooler Drum Percolator

This ‘Black Leaf’ pre-cooler cools smoke not only because of the recycling function – water is drawn into the smaller chamber and flows back into the main chamber through the second tube – but also by the integrated drum percolator. The inhaled smoke is softer and gentle on the lungs.

Due to the included adapter, the pre-cooler fits on bongs with standard grinding 14 and 19.
