Bong Percolator Boost Precooler | 10 cm 18.8 mm

The Boost attachment is mainly designed to cool the smoke and make the bong much cleaner after each session. How it’s working? Water is normally poured into the cap and it acts like a small bong, and due to the fact that the smoke begins to filter in the cap and not in the bong first, the smoke is cleaner. In this case, most of the crap stays in the cap, not the bongos.
