Turn up the volume on any smoke session with the Tophatter's Inc. Double Stereo Matrix Bong! Crafted from clear borosilicate glass, this awesome bong is designed to amp up the perc power. Smoke travels through the exterior fixed downstem into the double stereo matrix percolator stacked chambers one after the other, where the grid-like perc holes maximize diffusion and disperse smoke with a multitude of tiny bubbles. A 3 pinch ice catcher is also built into the neck for quick cooling and hits that go down smooth every time. Each bong includes a 14mm male herb slide. Multiple color accent options are available.
