Grav Labs - Helix Tube - Mini Beaker Base 7mm Glass Bong
Get twice the Helix smoke cooling power in this 12-inch mini beaker base Helix Tube from Grav Labs! Made in the USA (Austin, Texas) using 7mm-thick, laboratory-grade borosilicate glass, this bong set-up features the Helix funnel-shaped Venturi Chamber body on the tube and another on the included Helix Pre-Mix Chamber precooler. Micro-holes at the shoulders of the body are angled in the same direction and to create a swirling vortex of cooler, smoother smoke that's fascinating to watch and easier on your throat and lungs! This set-up comes with an 18.8mm > 14.5mm diffuser downstem and a 14.5mm one-hitter bowl. The acrylic joint clamp is NOT included.
