17" Triple Perc Scientific Glass Bong | Croia Glass

The Croia Glass 17-inch scientific glass bong is engineered for smokers who want maximum filtration, smoother hits, and a true high-end laboratory-style smoking experience. Built from premium borosilicate glass, this piece features a powerful triple-stage tiered diffusion system that combines a base inline perc, a large rocket-style tree perc, and a top secondary rocket perc. Together, these three filtration stages cool, refine, and condition smoke before it reaches the mouthpiece, delivering a cleaner and more comfortable inhale with the visual impact of an advanced scientific bong.
