'Black Leaf' Recycle Precooler

'Black Leaf' pre-cooler pre-filter

This pre-cooler of 'Black Leaf' cools the smoke not only through the recycle function - the water is pulled into the small secondary chamber when inhaled and flows back through the upper tube to the main chamber - but also through the adapter with NS 29 and drum percolator . This makes the inhaled smoke softer and more gentle for the lungs.
The pre-cooler fits on bongs with 14 and 19 mm cutouts thanks to the included adapter.
