Here is a solid, deep bong with lots of room for water and holes for percolation. Here at we call it the downstem and 12-arm tree perc, double chamber Diamond Glass bong, but you can call it whatever you would like.


Airflow moves into the beaker chamber through the downstem perc that has 6 d-slits and an open end for diffusion. Afterwards it moves up into the second chamber’s tree perc that has 12 arms, each housing 3 d-slits and an open end for diffusion. Finally the smoke/vapor is ready to move up through an optional 5.5” of ice and into the user’s mouth.


Want to convert it to a dab rig? Banger nails, downstems, and more available on our accessories page.
