SaleTHE SKYSCRAPER 2 — Black Leaf's spectacular multi-level bong delivers maximum fun. Made of high-quality borosilicate glass, it pairs diffuser slits in the downstem with FOUR tree percolators of eight arms each for thoroughly cooled, filtered smoke. Ice cubes can be added in the top chamber, and the 5 mm wall thickness protects the inner percolators and keeps this combo bong sturdy. The smoke swirls through the many chambers and the ice chamber before reaching the mouthpiece — impressive to look at and built for the most dedicated bong smokers.
