10" Hourglass Recycler Scientific Bong with Crown Perc | Croia Glass

The Croia Glass 10-inch hourglass recycler scientific bong is engineered for smooth circulation, continuous cooling, and refined scientific performance in a compact format. Built from premium borosilicate glass, this piece combines a precision Croia Glass Crown Perc, an upper hourglass-style funnel chamber, and a tapered return tube that keeps smoke and water moving through a controlled recycler loop. The result is a cleaner, cooler, and more responsive inhale with the elegant airflow dynamics expected from a high-end scientific recycler.
