This stunning dual perc bong from HVY Glass is constructed from 5mm thick Schott-Duran borosilicate glass for strength and heat resistance. The piece features an advanced multi-hole disc perc which combines with an additional 4-arm tree percolator for double filtration. The integrated splashguard keeps the spectacular bubbling action confined within the can, and a standard 18.8mm female ground joint and matching bowl slide complete the set up.

All-American Glass

The entire HVY Glass range tube is handmade by master flameworkers in the South Bay of Los Angeles from the finest Schott-Duran borosilicate glass. Each of these beautiful creations bears the iconic HVY Glass logo for authenticity.

Double Filtration

The primary disc perc in the lower chamber breaks up smoke, increasing the surface area for a smoother hit. However, with this scientific piece, the smoke is percolated again by the 4-arm tree perc before it reaches the mouthpiece for smooth, milky hits.

Clear Sci Glass

HVY Glass defines the sleek scientific glass look, allowing you to view the percolating action. The HVY glass name appears on the main can in clear, flame polished glass.
