Looking for that extra punch of percolation power? Massive tokes are silky smooth with the 12-inch tall Twin Matrix Chamber Bong. This glass bong boasts a dual matrix percolator setup that filters out contaminants and cools down the smoke not once, but twice and still doesn't create drag. Matrix percs are one of the more durable styles due to its compact design, so you can relax when passing it off to a friend. Blown from transparent glass with midnight blue accents, you'll have a front row seat to all the bubbling action. The curved neck and twin chamber design helps keep dirty bong water in its place. You can even turn this water bong into a percolated dab rig by swapping out the included bong bowl with your favorite quartz banger.
