Rock Glass Alpine Ascent 18 Inch Swiss Perc Bong

This Rock Glass bong puts two stages of percolation in one tall piece: a Swiss perc followed by a stereo matrix perc, with an ice catcher above them. It suits someone who wants smoke broken up in layers and chilled with ice, rather than a plain tube that does little to filter it.

More diffusion usually means a little more resistance on the pull, so this one is for people who prefer a filtered hit to a wide-open draw. Every piece has random color accents on the rim, base, and percs, so yours will not match the product photos exactly. If you like the look of Rock Glass, you can see more pieces in the Rock Glass collection.

The included male herb slide covers dry herb. For concentrates, check that your banger matches the female joint's size and angle before ordering.
