Grav Labs 9" Upright Upline Bubbler

Sold out

The 9" Grav Labs Upright Upline Bubbler is crafted with thick 75mm wall tubing, making this thing an absolute monster. The restriction to expansion within each stacked Perc creates a new chamber at each node wherein bubbles split, diffuse, and stack all the way up. The bubbler's flute also features three restrictions, uniting the aesthetic composition of the piece while cooling smoke as it moves through the ergonomic mouthpiece.
